Frequently
Asked Questions
Straight Talk From the Professional
Answers to the most often asked
questions about my knives
|
Do you make all these knives by yourself?
Short answer: Yes. Don't even think about kits, pre-cut blades, or
farmed-out components.
Long answer: I make everything you see here, except (obviously) the knives
in collaboration.
Rock in this case means gemstone, either solid
masses or groups of minerals that form semi-precious and precious
gemstone
Tool Steels are a special classification of
steels, made by special metallurgical processes, and must be
hardened and tempered
I start with a six foot long bar of annealed and spheroidized high grade
tool steel and a chunk of
raw rock. I profile, drill, mill, grind, heat treat, finish
grind, and polish the blades, I profile, shape, finish, polish, and attach bolsters and
guards. I saw and slab gemstone, cut, grind, drill, shape, sand, polish, and attach gem handles. I
do all the hand engraving you see here on this web site, I do all the machine engraving, I do all the high
resolution etching, artwork, and design. I do all the chemical processes, including
diffusion welding, etching, electroplating, electroforming, and two different types of
professional hot bluing. I do the gas tungsten arc welding,
the shielded metal arc welding, brazing, soldering, and multi-process welding. I sculpt
wax and cast bronze, silver,
brass, and nickel silver fittings. I make every part of the sheaths, the stands and the cases. No
other hands are involved in my knives! I build, maintain, and repair specialized shop
equipment, motors, machinery and controls, lighting, jigs, tools, and devices. I experiment with new techniques, apply
creative technology, and constantly strive to improve my skills and product. I do all the
photography, write everything on this site (except the
testimonials), build and maintain
this huge site with over 3800 pictures and over 100 pages,
and the multi-disc high
resolution CD ROM FlipAlbum catalog.
I also vacuum the shop floor of the metal swarf. It
is my full time job and has been since 1988.

How
long does it take to make a knife?
Short answer: As long as it takes.
A basic knife: satin finished blade, full
non-tapered tang, no bolsters, hardwood handle, and untooled leather
sheath.
Long answer: This is the most often asked question to knifemakers. I can make a plain,
basic knife in about 16 hours. Some pieces I've worked on for weeks, one in particular
cost me a year and a half. It depends on how much work goes into a piece. Engraving takes
extra days, filework takes hours, grinding through 12 steps takes many hours. Handle
finishing is done by hand, often the sheath work and stand are not even considered by the
curious when they ask the question. When you make everything by hand, including setting
up, repairing, sometimes building shop tools and jigs from scratch, knife making takes a
tremendous amount of time.
Sometimes the person who asked about the time is
considering just how much I get paid by the hour. You can see the little calculator
clicking away inside their skull, trying to figure my wages. They don't know about
materials and supplies, abrasives and electricity. They don't know about shop overhead,
machinery cost, material prices, and failure rates (yes, things break, wear out, and are
used up). Let me set this straight. I can make an inexpensive knife for about $8.00 an
hour. Yep, that's not much considering the decades of practice I have. Also, making $8.00
an hour in a shop with maybe $100,000 of equipment and supplies (see
the shop tour on the CD FlipAlbum here) and 30 years of training and experience
does not make sense. That's why I make knives that start at about
$600.00. This way, I can make maybe $10.00 to $12.00
an hour! You've got to love it; your not
making knives to get rich.

How long will it take
for you to make MY knife?
Short answer: Get in line.
Long answer: I used to
joke about the time in my career when I received an order a day, and now
it is a reality. There is no way that I can make a knife a day (see
How long does it take
to make a knife? above), so that means orders keep getting pushed
back farther and farther. Considering the investment value and quality
of fine custom knives, this is how it should be, and my clients
are willing to wait for fine hand craftsmanship, not hurried, with
attention to detail.
Please see
"Will you accept my commission
or order?" below.
A long time ago, I realized that if I hurry, I'll
make a mistake, and the whole project gets pushed back or worse, has to
be started over (eek!). In this world of instant gratification, I do
offer a solution for those who are unwilling to patiently wait for their
hand-crafted knife, sword, or project. Go to the finished knives for
sale pages
here and
here. There you will find
fine work that is ready to be shipped immediately.
For those of you
who've ordered custom work, the best thing you can do to help me out is
to be patient, and know that it will be worth the wait. If I've given
you a time frame for your project, please remember that it is just an
estimate, based on the current work load (which changes almost daily).
This is a hot topic, so I've given it its own

How
much do your knives cost?
Short answer: Prices start at $600.00 and go up from there.
Why?
Details here.
I use a strict pricing structure, based on 67
points of the individual knife construction. This way, I can
calculate exactly what work goes into a knife and offer a fair price
to everyone without guesswork!
Long answer: There is no standard fixed price in
the custom handmade knife world; all is variable. The first determining factor
is the overall size and shape of the knife, dagger, sword, or
artwork. Some blade shapes and sizes must be made from very thick or wide stock
which cost much more to purchase and more to shape and tool and
finish. Fullers, cannelures, and rip teeth add to the price. Once a style is
defined, the
cost of the knife
then depends on four things: the materials, the finish, the embellishment,
and the accessories. All of these points contribute to the cost of the knife
and also to the overall investment value of the piece over time. The more one of
my handmade custom knives cost, the greater the appreciation and value later on.
Materials: Making the knife blade out of O-1 oil
hardening tool steel costs less than high chromium high carbon D2 die steel, and
stainless damascus costs much more. The addition of brass bolsters costs more
than a knife without bolsters, nickel silver bolsters are more than brass, and
304 high chromium stainless bolsters cost more than nickel silver. Handle
materials vary greatly in price, and this must be recovered in the cost of the
knife. Micarta is less expensive than wood which must be hand-finished, and
gemstone may cost more. Gemstones can vary greatly in price, too.
Finish: The finish of each part of the knife
contributes to the overall cost. A satin or bead blasted finish on the blade is
less expensive than a mirror finish, and a textured bead blasted micarta handle
costs less than a brightly polished glassy gemstone handle. Note: I usually only bead
blast knives for military or tactical use where no glare is preferred.
Embellishment: Filework on the edges of a knife
blade add to the labor and cost, as does engraving, etching, artwork, carving,
and specific techniques that make a knife unique and valuable. Embellishment
cost and value varies greatly.
Accessories: Often, potential clients don't even think
about the sheath, stand, or case until late into the knife conversation. A plain
tooled leather sheath is less expensive than an exotic inlay in carved leather.
A military locking sheath with 38 components is more expensive than a tension
fit kydex sheath. A stand or case may add a lot to the investment value of the
knife, and as individual works of art, add more to the initial investment.
Take a look at your options on the
Custom Knife order form here.
You don't have to fill out the form to get an idea of the
range of value and options available in a custom piece. For more information on
these individual parts of custom handmade knife construction with many examples,
pictures and more in-depth details, here are some important links on this site:
Remember, there are many makers who won't even talk to you for less than
$3K I know of one guy who does the same looking knife over
and over, and he doesn't even consider making a knife for less than $7000!
Important: I use a strict pricing structure. It's based on
the size of the knife, the materials, the finish, the fittings, the handle
material, the embellishment, the sheath work: all these and over 65 other
factors are carefully figured into the cost of a knife. That way it's fair and
uniform across the board.
The prices of my current stock change from time to time.
The utilities, supplies, and materials I use to make
the knives go up constantly, as does the cost of keeping a piece current,
maintaining it on this website, or the utilities of storage, shipping, and care
costs as well as the costs of maintaining the storefront shop building, and this
website.
In addition to my costs, as my work becomes more popular,
the prices go up. Simply put, the more in demand a piece of artwork
is, the more valuable it is. This also helps my existing clients, who have
pieces that they expect to increase in value over the years. Their investment
value grows, and so does the value of my older works, whether in the hands of clients or
waiting on the website for purchase. Incidentally, my pricing structure for new
knives grows too, as does the basis and the cost of the 65 points I use to
determine price.

What's
the blade made of?
Refers to pattern welded high carbon and
stainless steel damascus
Refers to Crucible Particle Metallurgy Steels high in
vanadium and carbon, and high tungsten tool steels
D2 Extremely High Carbon Die Steel Critical Alloy
Elements: 1.65% Carbon, 12% Chromium, .9% Vanadium, .35% Manganese, .9%
Molybdenum, .45% Silicon
O-1 Oil Hardening High Alloy Tool Steel Critical Alloy
Elements: .9% Carbon, .5% Chromium, .5% Tungsten, .2% Vanadium, 1.2%
Manganese
ATS-34 High Chrome-Molybdenum Tool Steel Critical Alloy
Elements: 1.03% Carbon, 13.75% Chromium, 3.56% Molybdenum, .41% Manganese,
.025% Phosphorus, .25% Silicon
440C High Chromium Martensitic Tool Steel
Critical Alloy Elements: 1.25% Carbon, 18% Chromium, 1% Manganese, 1% Molybdenum,
.75% Selenium, .04% Phosphorus, .03% Sulfer
Short answer: In order of use, most of my blades are
440C, then
ATS-34, then
O-1, then
D-2, then
other
exotics and
damascus.
Long answer: 440C High Chromium Hot Work Stainless Die Steel is chosen for it's machinability, ease of care, and long lasting value. 440C is
one of the most often used knife
steels in the handmade industry because flat out, it's a great steel. It's
one of the most stain
resistant of the stainless tool steels, with up to 18% chromium and
up to 1.5% carbon. Not much will
corrode this blade steel, and it's tough and hard and wear resistant. No
tool steel
is rust proof, but 440C is about the best you can get for a
fine custom knife blade. Yes, there may be more stain resistant tool
steels, usually tool steels that have less carbon. These steels may be more
corrosion resistant, and are often used to make tough blades, not
necessarily hard blades. I go into the "toughness/hardness"
balance on by Blades page. For long lasting beauty,
440C has been the
choice for most of my knives, and for nearly all high end and sculptural pieces.
440C is used in more of my combat knives than any other of the
steels I use because it is proven to work well, limit corrosion, and be tough
and hard enough for combat tactical and rescue operations. There is a reason
that one knife blade analysis and testing site claims: Grade 440C
is capable of attaining, after heat treatment, the highest strength, hardness
and wear resistance of all the stainless alloys.
They may be overstating things a bit, but nonetheless, 440C
is a great steel. Just look at some of the finest knives made by some of the
best makers in the world. Many are using or have used 440C. It is a beautiful
steel, with a bright bluish chrome color when polished.
ATS-34 is essentially the same as 440C, but 3% of the chromium has been replaced by
molybdenum. So it's a little less stain resistant, but it's tougher. That means it's more
resistant to breakage. This is one of the high "chrome-moly" steels everyone's
heard of. The finish is comparable to 440C, and because of the additional toughness,
a thinner cross section can be ground for blades like double-edged tactical knives
without sacrificing strength. For the knifemaker, it's also harder to work with: harder on
tools, abrasive belts, and is more expensive.
O-1 is a great oil-hardening tool steel and is a high alloy
tungsten-vanadium tool steel that can be made tough,
hard, and extremely sharp. O-1 blues well, so tactical models and art pieces that require
a dark blade are possible. It's fairly easy to work, and prices are reasonable. Polishing
it is difficult, and different than the stainless tool steels. O-1 will rust if
not cared for; it has no corrosion resistance.
It can be hot blued for additional corrosion resistance. It's
great steel, maintains an
incredibly sharp, fine edge and is easy to sharpen in
the field.
D-2 is the highest carbon alloy tool and die steel
(thus the "D" designation) used in knife making. It has 12%
chromium so it doesn't quite classify as stainless and will rust if exposed to
corrosive moisture, acidic fluids (like orange juice or blood), and requires more
attention. But at 1.65% carbon, it can be made very hard and
is extremely wear resistant. The
finish on D2 is somewhat mottled with an orange peel appearance.
This is due to chromium carbides forming in the steel during heat treat, the very thing
that makes this steel so wonderful (most steels form iron carbides). D-2 is very hard to
work with, expensive, downright mean to abrasives, resistant to cutting and milling and
fabrication. So it's usually used for extreme use knives. It has a reputation of
holding an edge forever, and being impossible to sharpen.
This is an exaggeration, but the reputation is well-deserved. Most people cannot sharpen D2 in
the field or without motorized equipment.
I also use other specialty steels, like stainless damascus and powder
technology steel. Pattern welded
Damascus is decorative and beautiful,
but no matter how well it's made, those layers constitute welds,
potential places of stress in the billet. Although most of pattern welded damascus is
entirely usable, I don't use it in high strength tactical models, when a client requests
"shove it in a rock and stand on it" tough. The other specialty steels
that I use are expensive, hard to
work, and have definite applications, but each has characteristics that I don't have room
to go into here! They are RWL-34, W1, A2, BG-42, 440V,
CPM440V, CPMS30V, CPMS60V, CPMS90V, M2 and more.

Why
gemstone knife handles?
Short answer: They're the best.
Lapidary: the art and skill of cutting, carving,
sculpting, and polishing of precious and semi-precious gems, rocks, and
minerals.
Long answer: Okay, I make a lot of gem handled knives. In fact, I make more gemstone
handled knives than any other single maker in the world. That's rock, real stone, not the
plastic stuff that is made to look like rock and then called "stabilized."
That's one of my trademarks. I have a complete professional
lapidary shop nested in the
knife making studio, and I can start with a two foot diameter rock and cut it down to a
beautiful handle, brilliantly polished, and luscious to hold in the hand. Stone is cool,
hard, and dense, and the balance is perfect. I love gem for many reasons. It's impervious
to all chemicals that a knife might be exposed to. It has the same coefficient of thermal
expansion as steel (since
steel is a refined
mineral itself) and won't expand and contract
and eventually loosen on the knife like horn, bone, wood, plastic, and ivory do. It
doesn't absorb moisture, or oils, or corrosives that might stay there. It's hard, so it
doesn't scratch. Some gemstone can only be cut by silicon carbide or diamond. Gemstone
will outlast the knife blade in most cases.
Steel is made of Carbon, Iron, Chromium, Magnesium,
Selenium, Silicon, Tungsten, Molybdenum, Phosphorus, and other elements, all
found in rock.
Some people worry about toughness; that is, if they drop it on concrete will it break?
The knife blade TIP is the most likely thing to break on any knife so you shouldn't be
worrying about the handle. But just to soothe your fears, the stones are usually protected
in the critical areas by bolsters and the tang, or they are nearly as tough as the blade
(nephrite jades, flints, quartzes and jaspers). If the chunk of mineral makes it through
the cutting, grinding, and finishing process, it will last on the knife.
I thoroughly test the stone before using it on a knife
handle. I've
seen some beautiful rock that I can't use because it's too friable. In all the years and
all the hundreds and hundreds of gem handled knives I've made (see
over 1000 pictures of them in the CD catalog here), I've only had one small chip reported after
a knife dropped onto a stone floor, which was repaired like brand new.
Stone is tough. I
had one knife client return a knife to me for sharpening and reconditioning after years of
use and abuse. The blade was scratched and beaten, but the gemstone handle looked like the
first day it left the shop... amazing. And stone is beautiful. Nothing can match the
geologic creations of our planet for color, pattern, and texture. One of my complaints
about jewelry is that you can only see a small piece of stone, not getting a real feel for
the full pattern and characteristics, and you can't hold it. Gripping a dense
chunk of polished gemstone and steel in your hand is a wondrous feeling. When you pick it
up, it's cool and solid. After you put it down and pick it up again, it's still warm from
your hand. The feeling is delicious, the color exciting, the finish glistening.
The methods I use to attach gemstones to the handle
substrate are both mechanically and adhesively secure, in the thousands of
knives I've made, I've never had one standard gemstone handle fail. NOT
ONE.
Read more about that here.
There are
other Knifemakers who work with stone handles, and there is a lot of poor work out there.
Guys try to finish the stone without lapidary tools or knowledge and burn and pit the
finish. They misidentify inexpensive common stone as valuable, such as telling a client
that a piece of serpentine is jade (I've seen this a lot). They might finish a piece
without rounding and finishing and attaching the handle properly, that is, with cohesive
methods of jewelry bonding. I've even seen plastic rock identified as real gemstone, and
plastic amber called "reconstructed" because it has 10% "real amber
dust" in the acrylic! Real stone has millions of combinations of play and color and
light. It has imperfect lines, seams, and occasionally inclusions of other material. You
know it when you feel it, it's cool to the touch (or warm if it's been under lights or in
sunshine). To find out if it's real, you can tap it with a piece of steel and it
"clicks;" a piece of plastic will "thud." The ultimate test is heating
up a needle to dull red, then touching the handle. Plastic will melt and smell, stone will
laugh at your feeble attempt to burn it.

Testimonial: Eridanus
Jay,
the one thing you still can't get off
of the internet is the way a knife feels. I wish anyone
thinking of buying a Jay Fisher knife could hold Eridanus in
their hands for just a few moments. Then there would be no
doubt that buying a knife from Jay is the right thing to do.
I've bought some other blades of the internet that photographed
well, but when you got hold of them, they didn't feel or handle
like much. Eridanus just feels like it belongs in your hand.
You can get a knife anywhere, but this is a work of art.
Thanks Jay.
Oh and by the way the sheath alone is worth the price.

What
about horn, bone, ivory, hardwood, and plastic handles?
Short answer: I make those, too.
Long answer: Horn, bone and ivory can be described together. They are porous, so
require some care to prevent moisture absorption and drying. Continuous wetting and drying
caused only by changes in the weather will eventually lead to cracking and checking. Don't
even think about using them by the ocean! Some of the material can be stabilized or
surface sealed, and in ivory this is undesirable. Ivory ages gracefully to yellow and
check, which can be beautiful. There is also a difference in the coefficient of thermal
expansion between steel and horn, bone, and ivory, so this will eventually take its toll.
Keep them in a stable environment, and out of hot, dry light.
Beware of these
characteristics, and your knife will be fine. Mastodon, mammoth or "fossil"
walrus ivory are a bit more stable due to infiltration of minerals while buried. The
"fossil" term is used loosely in knife making, these are not true fossils,
because they are not fossilized, that is, replaced over millions of years by stone. A real
fossil is a rock, with all the characteristics of a rock.
When modern knifemakers use the term "fossil walrus tusk" or "fossil ivory,"
they are referring to ivory that has been buried in the ground for thousands or
tens of thousands of years and has absorbed some of the mineral stain and is
lightly impregnated with minerals that change the color and hue of the original
ivory. This hardens it somewhat, but it is still ivory. I also used petrified
ivory tusk, which is solid rock.
Hardwoods can be magnificent on knives, and are the choice of many owners and makers,
and I use them too. They are tough, resilient, and some are very hard. But they, too, can
absorb moisture, liquids, corrosives, and have a different expansion coefficient than
steel, which may lead to changes over time, and if severe, loosening of the handle.
So it's good to opt for stabilized hardwoods, or sealed hardwoods, or extra oily and resinous
hardwoods like cocobolo, rosewoods, ironwoods, and lignum vitae. Hardwoods are comfortable
to hold and most of them are light in weight, helping balance a knife. They need to be
attached with pins: for mechanical as well as adhesive fixture. The can be scratched, dented
and dinged, and some darken with age and exposure, but most of this change is moderated if
the knifemaker practices good application and sealing and finishing techniques, and the
user routinely cares for them (see "Care of your Custom
Knife" here). Learn more than you ever wanted to
know about hardwoods and stabilized woods used in modern custom knife handles on
my "Custom Knife Handles:
Woods" page here.
Micarta is a Phenolic, usually used as an electrical
insulator
I use plastics also, but usually only on request, and I never use "plastic
rock." Most of the manmade (plastic) material I use
is
Micarta®; it is tough, hard
phenolic originally created as a high strength electrical
insulator, and sometimes reinforced with linen
or paper. This is usually used on military knives and it is bead blasted or sandblasted,
for a rough, textured grip. Micarta is impervious to everything but heat, and it is
lightweight. But it is not exactly what you could call beautiful. It attaches very well,
is strong, and long lived. I've also used pure nylon on special projects, pure acrylic,
delrin, vulcanized fiber, carbon fiber, and even Teflon. These can be a good choice for
tactical knives. I haven't used "soft" grips like Kraton, because it
has to be molded onto the knife, and flexibility might lead to durability problems. Not
many of my clients ask for that type of handle, either. It
seems weak and short lived.
I use Kydex® for combat and tactical sheaths, which is a mixture of acrylic and PVC.
Colors available are black, gray, camo desert, and camo forest. I also use the polished
form: Concealex® These repel just about anything except high heat, and might become
brittle in Antarctica (see "Care of your Custom Military Knife
here).

ivory, and shell I use here.

Will it last?
Short answer: You'll be handing it down to
your grandson.
Long answer: My handmade custom knives are fine, well-made instruments and tools. The
fit and finish are excellent, so corrosion won't start. The materials are impervious to
just about anything you can throw at them. The woods are either decay-resistant or
pressure stabilized and sealed.
See a list of
hardwood materials here. Gemstones are sealed and impervious.
See over
290 pictures of
gemstone handles and lots of info here. Most of the steels
are stainless, the guards and bolsters are corrosion resistant or corrosion proof, and
attached with at least two zero-tolerance peened pins. Guards are closely fitted and
dissimilar metals are soldered. Pommels are tapped, threaded, and every piece is assembled
with jewelers quality water-clear epoxy.
See more about knife handles, geometry,
construction and materials here. Most of the knives will last 3 generations or
more, with reasonable care. See "How to Care for Your Fine Custom
Knife" here.
It is interesting to note that if
you have one of my knives that has a stainless steel
mirror polished blade, with 304 stainless bolsters/fittings and a gemstone
handle, the most ambitious care requires only an occasional dusting
and waxing. Most
gemstones will outlast the blades.
It gives me
great (if somewhat apprehensive) satisfaction that ninety percent of the pieces I make
will still be admired centuries after my bones are dust! They
will, however, continue to appreciate in value.

I've owned on of your knives for
about 5 years now. It was purchased at a fair in New Mexico,
and given to me as a gift. It's a small drop-point skinner, and
a beautiful piece of work! Not only is it a piece of art, it is
extremely functional and holds a great edge. I have put it to
the test quite a few times in the past years, and it has
performed flawlessly in every occasion. I'm proud to use it and
proud to show it off as well.
That little knife is perfect for
skinning deer and hogs though. Perfectly balanced, complete
control. I just wanted to say thanks for a
great product. Thanks for a great knife!
Very Respectfully,

Is it sharp?
Short answer: It's a knife. Of course it's sharp. Be careful.
Long answer: All knives have cutting edges. But so does an ax, a hand plane, and a
chain saw. Even factory knives have edges. What's the difference? The difference is in
blade geometry, an often neglected factor of knife making. In order for knives to be sharp,
they must be thin where the edge is relieved and maintained (that's the cutting edge). So
pay attention to the thickness right behind the cutting edge.
The blade should be
strong enough to take some use, but not abuse. It's a knife, after all, not an axe. The
key to good thin hollow-ground blade geometry lies in the skill and practice of the
knifemaker. Factories grind with CNC machines, or with jigs,
or with little kids in Pakistan, so they leave the blade
thick. This makes for a tough-looking knife, but after three sharpenings, it's so thick
that it now has a "chisel" edge, unsuitable for cutting.
Factories think that this is when you'll just go buy another knife. A properly hollow-ground knife blade is thin
throughout most of the blade, so that repeated sharpenings will still leave a usable, thin
geometry. Another factor of good blade geometry is in the method of grinding. If the maker
uses a jig, or has bad technique, he grinds straight across the blade,
neglecting the curvature or "belly" of the blade shape. This leads to thick and
thin areas of the blade: not good. Particularly noticeable
with this method is a very thick point, exactly what you don't need in a knife!
Why have a point if it's not thin and sharp? A skilled knifemaker grinding offhand follows the
curvature of the blade with the hollow-grind perpendicular to the edge
all along the edge,
leading to uniform thinness all along the cutting edge. This makes devastatingly sharp
bellies for skinning, dressing, or tactical knives. It also
makes thin, aggressive, extremely sharp points. Take a good look at that bulky factory
steel. Isn't it just a bar of metal that's dressed up to look like a knife?
See detailed drawings about cutting edges, relief angles, and custom
knife blades here. Learn more about sharpening and just what constitutes a
razor-sharp edge from the master of sharpening by linking to

Sharpening - The Authority" on the links page here.

Will it rust?
Short answer: Not if you take care of it.
Long answer: Different steels are different (see
"What's it made out of?" above). There is no "rust-proof" tool
steel. The addition of carbon to iron (to make steel) means that it can corrode. Steels
that are "rust-proof" do not classify as tool steels (like the
300 series steels
used in knives sold in late night infomercials), and they can be used as knife blades, but
they are weak and short lived. Sure, you might see one of them cut a soft tile then a
tomato, but their ability lies in the thin edge, which quickly wears away. They are very
tough (that's flexible, with resistance to breaking), but so is a spring. In fact, that is
almost exactly what they are: soft, thin stainless springs. You wouldn't take one on your
favorite deer hunt, or into the combat theater, or hand it down to your grandson. Other
corrosion-proof knives are dive knives. These are often made of 316 stainless steel, which
is used in making stainless pipes to carry chemical corrosives, such as acid. These won't
corrode, but having nearly no carbon, are also soft and weak and do not classify as tool
steel.
So some corrosion may occur on fine stainless tool steel knives, but only if
you let it (see
my number one complaint below). A high quality 440C stainless knife steel will only corrode if left
exposed to sea water (for a long time, longer than a day or two) or orange soda
pop, or battery acid, or left in a wet leather sheath (acids are used in tanning
leather) or stored long term in the sheath and not allowed to
breathe. ATS-34 is a bit less corrosion resistant, so blood, orange juice, etc.
will also stain it. D-2 is even less corrosion resistant, and I've seen peoples
acidic fingerprints etch into the blade
finish. And O-1 will flat out rust, unless you keep it coated with car wax, or
Break-Free®, or silicone-based polish-sealants. A high mirror polish on knives can help,
as debris cannot cling to the blade.
So what to do? Clean your knife, keep it reasonably
dry, and it will be just fine. See more about knife care here.

What about blued blades and coatings?
Short answer: They're dark.
Long answer: Several clients have asked why active duty military would
carry mirror finished blades into combat where they lack "stealth." I explain
that some of them are spraying the
knives with camo paint, sheaths and all, then washing it off with
lacquer thinner when they return from their deployment. This way they've protected the finish
somewhat, and had something very nice to hang on their wall afterwards, eventually to hand
down to their children. Others leave the blades polished, and
figure if they have to pull their knife, the situation has already gone to hell
and some shiny high-chromium tool steel might make an influential statement.
I do not coat blades, because that would hide
the grinds, hide any potential flaws, and eventually chip and peel.
I go into detail about this topic on my Blades page at
this
bookmark.
Bluing is a process of oxidizing ("rust" is a form of oxidation,
uncontrolled and irregular). Hot bluing (which is what I do) is a controlled, deep passive
oxidation process whereby the steel is cleaned thoroughly, chemically and
molecularly, then immersed in a superheated boiling solution of sodium nitrate and other
salts for 40 minutes or longer. This oxidizes the first several thousandths of an inch of
the steel surface, which is a very deep penetration. The bluing process is the same used
on all fine firearms, that black dark look that takes years to buff, scrape, or polish
off. My process excels in penetration, where most firearms might be blued for 10-20
minutes, I start at 40. To give you an illustration, when I cut my makers mark into a
blued blade using a sharp stylus diamond point engraver at 50 pounds per square inch, it takes three
full passes to cut through the bluing to achieve a bright cut! To sum, hot caustic bluing
is a well-recognized, time-proven method of inhibiting corrosion (not
preventing it) on
the surface of steels. My own son (in the 101st Airborne) has
carried a hot-blued skeletonized
knife in combat in Iraq. So has his
squad. They're very happy with the performance.
That being said, please remember, there is NO corrosion proof tool steel.
Even 440C, which contains 17% chromium will rust and corrode in salts or acidic
environments. Please look at my "Care of Your Custom Military
Knife" page on this website and "Will it Rust?"
above.

What about blued stainless
steel blades?
Short answer: Can be done, but why?
Long answer: There are several methods
for bluing stainless steel. They are complicated and expensive, compared to the
standard process of bluing carbon steels (see
"What about blued blades and
coatings?" above). First, please consider why stainless steel is "stainless"
in the first place. It's because of chromium, and we're all familiar with the
permanence of a chrome plated bumper of a car (though newer cars are plastic,
yecch!). Chromium steels are resistant to corrosion because they form a passive
oxide coating at the surface as soon as it's exposed to the atmosphere. Aluminum
has a similar property. So corrosion (rust) does not easily start. The most
common reason to blue a blade is to impart a corrosion resisting "controlled
oxidation" to the surface of the steel, that way it inhibits further
corrosion. Since true stainless steels contain a lot of chromium (more than 13%
to be classified as "stainless"), they are already more resistant to corrosion
than a blued steel. So the only reason then to blue a stainless steel blade is for color and
appearance.
Currently, I do not have enough
requests to add an additional and expensive bluing bath for stainless
steels to my already huge list of processes. I get requests for blued
stainless about six times a year, and that is not enough to offset the
cost of the chemistry, tanks, and process, a cost that ultimately, I
would have to pass on to the clients. Also, from what I've determined by
study, the blued stainless tool steels have a questionable and
variable appearance. Perhaps in the future it will be worthwhile to blue
stainless tool steel blades. Right now, it's not just cost effective,
and no advantage for corrosion resistance is obtained.

Is
there an ultimate blade?
Short answer: NO. Read, study, ask, learn, and make the best purchase you can afford
for your intended use.
Long answer: Lots of claims have been made. Since ancient times, man has marveled over
the properties of the cutting edge, and then sadly, discovered its limitations. I can
imagine that the first obsidian swords made by Meso-Americans were incredibly
scary, until they hit another rock, or sand, or dirt, or Spanish armor, and the
sharp flakes of obsidian were broken off. Early steels seemed wonderful, but
wore down easily, and rusted, and bent, and broke (often in battle ...oh,
crap!).
Sure, we all hear of near-magical properties of Japanese swords, until we
realize that they are folded 80 thousand times to get the grain to run straight
in the metal, because it's so crappy and random to begin with. And that they
used differential tempering because the cutting edge would be too soft, and the
spine too brittle if they didn't. We've heard of magical blades of the Persians,
Arabians, Chinese, and (let us not forget Excalibur) the British. Most of us
know this is fairytale stuff, but some hold out the hope that there will be a
"super material" that will someday be the ultimate last knife you ever need. It
will stay razor-keen forever, be feather-light, be super-tough, never break or
bend, never corrode, and never be lost, staying by your side like a perfect
extension of yourself, like an accessory of your hand. But until that day comes,
ceramics, titanium, super steels, and experimental blades will all have their
limits. Every edge dulls. The pressure per square inch that is placed on the
cutting edge can be enormous, the abrasion horrific. Even the hardest
titanium-nitride coated ceramic metal cutting tools will dull (and they
are extremely brittle). There is no alloy strong enough to lift a truck, yet
light enough to weigh a feather. That's science fiction. Oh, yes, additionally,
we would prefer our super material be cheap-
|
Some wisdom:
Look, there are
many good knife steels out there. When sites and discussions go on and on about
steel types and properties, ad nauseam, they are often ignoring
balance, fit, finish, geometry,
accessories, service, and design. Don't get distracted by steel property
details! The steel is just the start of the knife, not the whole. If it were,
every knife maker in the world would be out of business, not buried in back
orders and very expensive projects. When you see this type of site, ask to see
their knives. That will tell you a lot!
|
So we're all adults here; we've used knives to cut. Some are much better than others,
and they cost more, some are more beautiful and comfortable to use, and they cost more,
some are cheap and ugly and common. There is an entire range of types, anything to fit the
value you place upon your knife. Just beware all of the hyperbole. Knives and magical
properties seem to go hand in hand with snake oil and cures. It's simple enough to know
that there are only a handful of fine tool steels used to make high quality custom knives,
mainly 440C, D2, ATS-34, RWL-34, BG-42,
A-2, O-1,
W-1, S30V, 440V, S90Vand custom Damascus. They are
the most
commonly used steels for fine knives for a reason. Read, study, ask, learn, and make the best
purchase you can afford for your intended use.

Do you make throwing knives?
Short answer: Why toss your weapon in
the direction of your enemy for him to pick up and use?
Long answer: "Projectile"
tools. "Throwing knives. You will hear all kinds
of hype about super-duper knives that can be thrown, but this is Hollywood
cowboy talk. I would begin to question why you would toss away (perhaps
even in the direction and to the benefit of your opponent) your edged weapon
in the first place! I don't make knives for throwing. The reasons are these:
Throwing knives are usually "throwaway" knives, in that they're made of a
cheap and soft steel, so that when you hit that occasional rock or concrete
(which will inevitably happen if you're practicing throwing a knife), then
they will just bend, not break. That requires them to be soft or springy
steel. Imagine if the first time you threw a knife and hit a rock, a chip of
metal broke off your blade or point! The proper temper of a true knife (in
layman's terms) is for the knife to just get to the point of bending when it
breaks. Often, knives are tested this way: the knife blade is clamped in a
vise, pressure is applied to the handle sideways until the knife bends
enough to snap the blade in half. Around the break, there should be just the
initial signs of permanent bending, and the break should be clear, fine
grained, gray metal. This is a simple old test, that generalizes the
hardness and temper of the blade.
Nowadays, knifemakers should grind the
knife for the best cross-sectional geometry of the knife, considering the
use and steel type and manufacturers design data. The results are the same:
for a knife to be hard, the steel will sacrifice toughness.
Get details of the hardness-toughness relationship on my
Blades page at
this bookmark. For the knife to
be tough, hardness must be sacrificed. It is a careful balance, as there is
no material that is both very hard and very tough when ground thin enough to
be sharp. To understand this better: hardness is the resistance to
penetration, and toughness is the resistance to breakage. An
extremely tough
knife is a soft knife, so that the steel can bend
instead of breaking. An extremely hard knife is a brittle knife, so that the steel
cannot be penetrated. Both extremes cannot be achieved, but only balanced as
closely and carefully as the particular tool steel will allow. That is my
job. So if I made a knife for throwing, it could not be hard (throwing
knives are usually butter-soft), and if I make a proper hardened knife, it
would be too brittle to throw. The only way to possibly balance this is to
leave the steel thick, and then it cannot be made very sharp, and future
sharpening would be impossible.
Now, that does not mean that a knife couldn't be thrown in an emergency.
Just like chopping (which should be left to an axe), it might occasionally
happen with a custom or tactical knife. I simply cannot guarantee a knife
that will be thrown or used for heavy chopping. Ultimately, if I make a
knife for you, it's your call how you use it. I'll just make the finest
knife for cutting, slicking, and defense
(in combat knives) that I can make with the
available materials. I do not make knives specifically
for throwing. If you must have a throwing knife, you should make one
yourself out of a piece of rough stock, as it will probably be ruined anyway
the first time you hit a piece of concrete, dirt, rocks, or hard wood. Or you can purchase
them cheaply from numerous import companies here on the web for cheap, just
do a search. Read more about professional steel treatment,
grind geometry, and custom knife blades on the
"Blades"
page here.

How
important is heat treating?
Short answer: Very. It's the whole banana.
Long answer: The reason I started making knives is because when I was
young, I heard about the secret of
steel: The fact that steel could be heated and cooled at
different temperatures and rates, deriving a piece of metal that was dozens (sometimes
hundreds) of times softer or harder than a piece cut from the same bar. It amazed me and
an old welder said, "If you want to learn about heat treating, make a knife."
He was right. I started annealing springs and "found"
steel stock, and every piece of steel I could get my hands on. And I studied. (I've done a
lot more, too. Read a bit about my past here.) What I found was that
there was an entire science of the crystalline structure of steel: how it forms entirely
different components based on metallurgy, mixtures, exposures to heat, duration, and more.
Tool steel is not just steel, it's martensite, austentite, pearlite, cementite, and
trootsite. It's carbon, chromium, silicon, manganese, magnesium, tungsten, vanandium, and
sulfur. It is a complex scientific field of study and practice, and as a knifemaker, I'd
better be trained. So I studied, experimented and learned some more. I've built half a
dozen modified ovens over the years, and I realize that the heat treating is still the
heart of knife making. I heat treat in vacuum-nitrogen quenched inert gas electric
high-intensity rapid ramp ovens. I heat-treat specifically as the manufacturer requires,
and modern tool steels are made in laboratory-like conditions, so that is how I treat them.
You might wonder why I do all my own heat treating and don't trust it to an outside
contractor, as most knifemakers do.
- When you trust an outside contractor, you admit
you can't heat treat a knife blade properly. That is a good thing,
I suppose, because I know of
several well-known makers who won't admit that, and produce inferior knife blades because
they don't follow clean, laboratory-like conditions.
- You are at the contractor's whims as
to timing. What if a military client needs a combat knife in a hurry? You both have
to wait on the heat treater.
- You don't know for sure that
the heat treater is heat treating per
the manufacturers recommendations, such as a long pre-soak at a specific temperature to
relive machining stress.
- You don't know that he soaks for the correct time at the
critical temperature (or that he even reaches it!)
- How does he quench? Does it
produce stress risers in the blade at the precarious points like the choil and bolster pin
corners?
- Does he double temper for the right amount of time as per manufacturers
recommendations?
- Does he do a deep sub-zero freeze at or between
quenches or tempers to minimize retained austentite?
- As each manufacturer has slightly different processes, how does the
private contractor know all of them? He's not cutting corners or "generalizing"
to make a buck, is he?
- Does he set the temper depending on the blade grind
geometry, the steel type, and the intended use? Or does he just set it at
Rc58?
- Can he and does he apply a differential temper, or a
graduated temper, if the specific design requires it? He can't and won't.
- Does he test each and every blade with a professional
certified testing apparatus?
Who knows about any of these items? I don't, so I trust myself to do this critical set of
processes, not an outside heat treating contractor.
Most heat treaters set the blade at one hardness: 58 on the Rockwell C scale. I have
blades that range from 54 Rockwell C for heavy choppers that must be shock resistant
and tough to 55 Rc for springy, flexible fillet knives, to 56 for very thin ground
moderate light trailing point blades, to 57 for standard but thinly ground knives with a
light cross-sectional profile, to 58 for many standard knives, to 59 for harder, thicker
tactical models, to 60 for short and robust small folders and heavy-spined knives, to 61
for special purpose cut off blades for hazardous materials rescue and light metal cutting.
I even have blades that are differentially heat treated and tempered, for a range of
hardnesses along the blade! Where I set the final temper depends on three things: the
manufacturers type of steel and his recommendations, the geometry of the grind and the
cross-sectional area, and the client's intended final use. I can't see an outside
heat-treater working with a hundred custom knife blades all from different
makers knowing these details. Read more about the Rockwell
hardness scale on the Blades page at
this bookmark.
And factory knives? Makes me growl. A group of USAF Pararescuemen brought me some
factory made knives they'd been issued. They claimed that the edge "rolled" when
used. I'd never seen such a thing, so I got permission to do a diamond penetrating
hardness test on them. They were 100 times softer that they should be, that is: they
weren't even heat treated! Then, a friend took one to a metals analysis lab, and found out
the steel (which was marked right on the blade "ATS-34") had none of the
percentages of alloy components of ATS-34. They didn't even know what
the blade steel was! And this
factory sells thousands and thousands of knives a year. By the way, there is no law
preventing a factory from stamping anything on a blade (except gold
"kt" marks).
Read more about knife manufacturers' dirty
little secrets and custom knife blades here.
Look, there are a lot of good heat treaters out there. Several can do a splendid job,
producing repeatable fine results. I just don't like my blades leaving the shop and not
knowing just what someone is doing with them. So, since heat treating is a very important
part of knife making, I learned how. The buck stops here. I buy my steel from a reputable
supplier, and It's done right here in the shop, it's tested
for certainty, and it's done right.
I guarantee it.

What if
I lose it?
Short answer: Don't. That really sucks.
Long answer: I've heard guys say for years that they won't buy a fine knife, because
they'll just lose it. Why is that? Perhaps they lost some knife in the past and were
heartbroken about it. I'd look at that heartbroken emotion with a little more
intent. The knife they lost meant something, maybe it was irreplaceable. Perhaps it was a
knife handed down through the family, or it dressed a particularly fine animal on a mystic
hunt, maybe it still had the tobacco stain that grandpa left on it, or maybe it was just
the right shape, or had a really nice edge, or was just plain sweet. What did
they do, set it down on a rock and walk away? Did they have it in their shirt pocket and
bend over and have it fall into the lake? Did they shove it in a locking sheath, but not
tug it to make sure it's locked, and lose it while crawling through the brush in a combat
training exercise? All of these have happened with fine custom knives I've made, so that's
why they're cited here.
For every knife lost, there are thousands and thousands that are still in use, so the
chances are slim. Besides, what other tool might you carry and lose? A compass? A fishing
rod, a rifle? Not likely, because you've got a good hold on them, you check to make sure
they're secure, you value them. Just keep this in mind. If you're lost in the wilderness,
with only one hand tool, what would that tool be? How important is your knife? How
important is your life? You might want to think about the knife you carry and it's quality
now. And don't use that lame excuse for not owning a fine knife. It's just another way of
saying "I'm too irresponsible to own a fine custom knife." Ouch!

What
if it's stolen?
Short answer: Somebody wants your knife. Lock it up.
Long answer: Knives are an "attractive" nuisance. This has been illustrated
several times by gallery owners who refuse to display knives in their showrooms. Knives
are frequently locked in display cases, secured behind glass, locked in vaults, covered,
hidden, and protected. It might be that they're small and easy to carry away, but that's
not the whole story. Knives are valued by everyone. Not everybody can fence a diamond
tiara, but everybody wants a fine knife for themselves. The knife is universal, beautiful,
and handy. Fine knives by custom makers are some of the most valuable small non-jewelry
items made. And some of them are jewelry, with gold, precious gems, and exotic
metals dripping with elaborate embellishment. I've seen it at every show, people drool
over fine knives. Someone wants your knife.
I remember a particular show in Colorado Springs where 80,000 people strolled by my
table over one weekend, all with lust in their eyes. There were constant attempts to
divert my attention for the quick grab and smooth blend into the crowd, but I was extra
vigilant. It was a truly awful show. It was like bringing your teenage daughter to a biker
bar. I also know of entire collections being stolen.
Fine custom knives by a well known maker are one of the highest appreciating
investments one can own. They typically appreciate 10-25% a year or more. I sold one knife
for $750.00 and the next year a gentleman told me he purchased it from a dealer for
$4000.00. This also illustrates the point that the cheapest place you can buy a fine
custom knife is from the maker. After a dealer gets his hands on them the price goes up,
up, up. Knives are valuable. Custom one of a kind handmade knives by a well-known
established maker are irreplaceable. Keep an eye on them. Learn more about "What is the
value of investment knives and why?" here.

Why
are blades so different?
Short answer: They're used for different things
Long answer: Knives come in thousands of varieties. That's why I've got over
300
patterns on this website.
You can see them all right
here. When you think about how you might use a knife, and how many types of knives you
would like to own, multiply that by how many people are using knives. Think about how
another professional might use a knife. Someone once said that everything we eat, own, or
use in any way has been touched by a cutting edge. So there are blades for each of these
tasks. In custom handmade knives, each handle must fit a different hand. And the balance
must vary, depending on the use. A heavy blade (blade-heavy) knife might be used for
rescue work, light chopping, and in a pinch, digging. A handle-heavy knife usually denotes
delicate work, a light thin blade, scalpel-like tasks. There are different grind
geometries, like hollow, convex, and straight. There are a large variety of teeth, hooks,
and serrations. Some people might prefer a long handle, some a short one. Knives might be
held in a variety of ways in the hand, and there are different hands. It is absolutely
bewildering the different kinds of knives history has given us. Knives may range from a
simple shank of metal with a cutting edge, to high art sculpture that is based on a knife,
but will never be used to cut. Read more details than you asked for
about custom knife blades, geometry, manufactured knives, cutting edges, and everything
pertaining to the custom knife blade here. Then, if you ever get through that page,

Folding
or Fixed blade?
Short answer: One folds, the other doesn't. Both are nice, one is stronger.
Long answer: Okay, this one has inspired argument for decades. Here's the straight
skinny. If a knife is to be strong, very strong and tough, used in tactical, rescue or
lifesaving operations where the durability of the piece is tantamount to survival, a full
tang knife is the only way to go. That's because it's one solid piece, from tip to tip. It
is usually reinforced at the critical points, the bolsters. It usually has a fully tapered
tang, making the blade tang (the metal under the handle scales) lighter at the carrying
end, but thick and strong at the spine (the thick part of the back of the blade). A
folding knife has one major deficiency: the pivot. History and experimentation have given
us many ways to reinforce, strengthen, make rigid this tenuous pivot, but let's face it,
it's still a tiny piece of steel holding a long levered blade. Also, no matter how it's
done, the handle is always longer and larger than the blade. That's why you don't see any
huge folding knives, because a handle-heavy knife is usually used for light, scalpel-like
cutting, and a blade-heavy knife for stout work cannot fit into the handle (see "Why are blades so different?" above).
Also, the locking mechanism which should reinforce the pivot must move, and be moved by
simple finger pressure, so it cannot be too large or apply a lot of mechanical pressure.
Numerous tests, like applied pressure, palms on the spine,
spine whacking, and torque pressure have been devised to make sure that a
folding knife is not going to close on your fingers in a critical situation, but
why even take that chance? I cannot imagine a folding knife even being called
"Tactical." And I can't imagine a folding knife rated as CQB (close
quarters battle). That is why you won't find any folding knives on my
tactical, combat, or
military knives pages here.
Picture this: your life depends on your knife.
Situation A: a neighborhood criminal or perhaps even an
enemy combatant or terrorist wants to kill you. You whip out your- folding
knife? Flip and click and he's facing a 3" blade secured by a 1/8" (or less)
thick spring and a hollow handle... what then?
Situation B: You've somehow got lost in the woods, and
need to find or build a shelter. You might be there for several days, it's
raining, you're hungry, and there are nothing but big thick trees around and a
lot of silence. You whip out your 3" folding knife... oh, yeah, you're not
alone. A family member is with you and they're depending on you to save their
life-
The best thing to have in both these situations is: a
concealed firearm in situation A, and a full set of woodworking tools (chainsaw,
axe, firestarter, etc.) in situation B. Barring that, you'll have to do
with what you carry. Why do I bring up situations that probably won't ever
happen? I've got news for you, my friend. Both situations have happened to me.
In situation A, I happen to have a machete nearby. Guess what? The standoff
ended immediately. In situation B, I had a sheath knife, big enough to hack away
some small branches, build a fire to keep us warm, and eventually build a signal
fire days later.
Now that doesn't mean that folding knives are useless, quite the contrary, they have been
refined to wonderful and beautiful instruments, deserving
fine art status. Some of
the most valuable knives of collectors are folding. But the difference is clear: they're
weaker at the pivot, and the handle is larger than the blade. So the
fixed blade knife is
stronger, period. And the blade to handle length can be varied
for proper balance.

Full
tang or hidden tang?
Short answer: One tends to be rounder, one flatter. One is stronger. Both are nice.
Long answer: A full tang knife is a solid piece of steel from tip to tip (see "Folding or Fixed Blade?" above). The
full tang is usually bolstered (reinforced) at the critical points, mainly the ricasso
(where the blade joins the handle) and sometimes at the butt (where it might be bumped or
tugged out of the sheath, or a lanyard tugs at a hole). The full tang is tapered in most
fine knives to reduce weight, align the balance, and look really neat. Handle
"scales" are attached with pins, rivets, or screws to the flat side of the tang
between the bolsters. The bolsters are usually dovetailed to lock the handle material
under an angle and to strengthen the whole handle arrangement. A full tang knife is a
strong knife, but it is usually "flatter" in the handle due to the design of
scales, and the need to balance the tang weight against the handle material.
The hidden tang has two basic types, both of them make the tang invisible. One type has
the tang extending down through a milled guard which is sometimes pinned and/or soldered
against the rear of the ricasso. The tang is either threaded or a threaded rod is brazed
or welded to the blade tang, and the threaded rod extends down through the handle
material(s) into a threaded pommel. This allows a more "sculpted" and rounder
handle, and the handle may be made of one large piece of material that can be seen
"in the round," or many pieces of material stacked like doughnuts onto the tang
thread and then finished at once (some makers call this a "stacked tang").
Because of the reduced tang size, and sometimes attached joint, the hidden tang is
somewhat weaker than the full tang. It is usually used on non-combat, non tactical knives
that are not expected to suffer great stress. Skinning, field dressing, utility, and light
duty where a round, comfortable handle is desired necessitates this design.
Another type of hidden tang does not have a pommel. The handle material is drilled, the
tang is shoved into the hole with plenty of epoxy, and sometimes a pin is driven through
the hidden tang cross section. This method is used mainly on handles like stag
horn, where
the shape of the butt must be left natural. It is the weakest of the tang types but can be
quite beautiful and functional.

How do I fit the handle to my hand?
Short answer: Size does matter...
Long answer: Most hands are close to the same size. Sure, there are
differences, and occasionally a client wants a knife to match his hand precisely, usually
on tactical or advanced bladed weapons, combat, or rescue knives. These are situations
that require a locking fit between the fingers. I had one client, years ago, that was a
boar hunter. To the unanointed, these guys corner the boar with dogs deep in the southeast
U.S. swamps, then rush up with a knife to finish it off. Sometimes the knife is lashed to
a stick, but why bother, after all, you're not there to be safe... I like the up-close,
personal nature of this encounter. The boar is fighting for his life, the hunter is just
out for a day of sport. Anyway, the knife had to fit his hand precisely; as you can
imagine, a dropped knife in this situation is .... embarrassing. So he came into the shop,
shaved off each thirty-second of an inch to get it just right to fit his hand. But he was
the exception. Most of my knives fit most people's hands rather well, as there is a lot of
experience from your knifemaker having to do with balance, feel, texture, and a host of
manual artistic adjustments that are too deep to describe here. Let's just call it
practice. I see the pleasure in their eyes as soon as the handle hits their hand.
Occasionally, a client does need a specific adjustment to fit his hand.
There's an easy way to do this, which is usually only necessary on a handle that has front
and rear quillions (that's the part that stops the fingers from sliding forward onto the
blade). Here's how to adjust it for you: wrap your fingers over a ruler, as if you were
wrapping four fingers over a horizontal rope. Measure the width between your center
knuckles (the ones you would knock on a door with). This measure is the quillion width.
For a tight fit in your hand, round the measurement down to the nearest 1/4"
For a looser fit, round up to the next nearest 1/4"
What could be easier? To get really precise, and to see
illustrations of the hand measuring process and how it applies to the knife,

How do I
carry it?
Short answer: In a sheath, of course.
Long answer: If you carry a fine knife, the sheath is the most important thing! What?
How can this be? (We'll exclude folding knives for this conversation) So what's a sheath
for? A sheath's number one purpose is to protect the wearer from his own knife. Surprised?
You thought it's number one purpose is to carry the knife, right? A knife, a good knife,
is a sharp instrument capable of vicious damage. It will cut you if you drop it, fumble
with it, let it slip, fall, trip, bump, or even touch the cutting edge (you do keep your knife sharp don't you?). So it's important that
it stays sheathed until you're ready for it, then it must be immediately accessible. This
is actually quite a task we ask of the modern knife sheath. And believe this: most modern
Knifemakers have woefully neglected this most important part of their trade craft.

What are the characteristics we should look for in a modern sheath? We want the sheath
strong, so that it doesn't bend. Don't buy a knife sheath that is flexible, it will give,
and the knife will not, and the knife will poke through right into your fleshy parts!
That's why I use 9-10 oz. leather shoulder in most of my leather sheaths. It's just one
step below shoe sole leather, and I stiffen it as much as possible. In my military and
professional tactical knives, I use Kydex®, but not just Kydex alone, I make the sheaths
with aluminum welts, bonded with waterproof cement and Chicago screws. Our sheath must
also hold the knife. Leather has it's own frictional component, usually bearing on the
bolster area of the knife, snuggling up the knife in it's cozy "sleeping bag."
Military grade knives can utilize Kydex the same way; the Kydex is hot-formed around the
knife and can actually be formed to "lock" the knife into the sheath with an
audible "click." Some military grade sheaths use an additional snapping
retaining strap of leather or ballistic nylon or other material to secure the knife. The
ultimate knife retainer is a positively locking mechanism
in a combat grade sheath; mine are made of stainless
steel, milled and machined right into the aluminum welts, reinforced with the Chicago
screws, and are waterproof (but then, I've got the best locking sheaths made, period).

The sheath must resist the elements. With a leather sheath, there are a few things that
the professional maker can do; I seal mine with waterproof lacquer, and use artificial
sinew (100% polyester) to stitch the sheaths. But leather cannot be made waterproof, only
water resistant, so that is it's limitation. On my military and tactical sheaths, Kydex,
aluminum, and nickel plated steel Chicago screws are waterproof, so that's that.
The knife must also allow accessibility. The design of the knife helps, a "hawks
bill" rear finger quillion at the end of the handle allows easy removal from the
sheath. The sheath may be worn in a variety of ways, even opposite side cross-draw at an
angle. Snapping flaps of leather sometimes are used to protect the handle, but ease
removal. The ultimate accessibility is the locking sheath, because it exposes the entire
handle, and just sheaths the blade. The sheath must also protect the knife. That is why
the most protective sheaths are deep, that is, the knife drops way down into that pocket,
and that keeps brush and materials from bumping, snagging, and bruising your investment.
The flaps (if used) must fold to the back of the wearer, so they don't catch on tree limbs
and open up while the wearer is moving through brush. The belt loop must secure the sheath
close to your body, for the same purpose. Some long knives have angled belt loops to
prevent the handle from jamming up under your ribs when you sit in a vehicle.
The sheath must protect the cutting edge. Yes, that's why you have the knife in the
first place, so how is that done? In leather sheaths, the welts (the layers stitched and
held between the front and back of the sheath) are thick and stout, mine usually have
several layers tapered into the deep well of the sheath, with a visible "ramp"
of welt to protect the sheath and blade as it is inserted and withdrawn. The military
types have welts of .1875"-.250" thick corrosion
resistant aluminum.
And the sheath must look good. For me, that means commensurate with the quality of the
investment of the knife, featuring inlays of exotic skins like ray skin, snake skin,
hippopotamus, gazelle, antelope, and shark, with fine tooling, airbrushed finishes, and
some carving. The military models often have descriptive removable engraved lacquered
brass flash plates designating operational units or slogans matching the knives. A
significant thing to remember is that the sheath is seen more often than the knife, so it
very important to pay attention to the aesthetics. How many makers apologize for their
sheaths? Learn more about custom knife sheaths here. If fine art

What is the value of
investment knives and why?
Short answer: Try to make one and you'll see.
Long answer: Fine custom knives by well known makers are some of the most valuable
collector's pieces. The custom maker makes everything by hand (assuming you're not fooled
by small production shops using a makers name). He may produce 10-100 knives a year, and
his life is limited. There will never be thousands of a particular model, and some makers
never even make two knives alike. The value is directly attached to the maker's name, and
the name is the most important thing. So what's in a name?
There are many makers in the world. Some say as much as 3000 in the US alone. Though
that number seems large, let's really look at it. That means that .0012% of people are
Knifemakers. That's one in 83,000 people. Of these, most are "garage" makers,
that's beginners, hobbyists, or retired tinkerers who've made a couple of knives, or made
for a year or two, and nibbled around the edges of knife making. About 300 of these are
serious, committed, professional makers who are at the "top" of the collecting
desires. That means one in 830,000 people. If that maker has a career that lasts 20 years,
and he only makes 50 knives a year (that's probably more than average), that leaves 1000
knives with his name on them. If we figure ONLY the collectors in the US, their chances of
purchasing a knife from this favorite single maker are 1 in 5,000,000 in any given year.
Wow. And what collector only wants one knife? As collecting of fine custom knives grows,
these odds are bound to decrease (Incidentally, what do you think the worldwide odds
are?). So there are some numbers, but it's not just numbers.
As technology increases, and "works of art" are cranked out by computer
assisted devices, the desire for handmade objects carefully crafted with attention to
detail, high beauty, and originality increases. I call it the "too-tech" effect.
Mass machining, mass marketing, mass appeal leaves a hole in the collector's soul. This
rebound effect is no better seen than in the millions of mass-produced factory knives
touted as "collectible" because they feature a cheap cast version of a popular
motorcycle brand (made in China), or a factory etched "commemorative issue"
design on the blade, or because they follow a design that was popular in a recent motion
picture action or sci-fi film. How will these knives appreciate over the years? You'll
have to live two hundred years to cash in on that, friend.
Custom handmade knives, however, appreciate 10-30% a year, and many dealers and
purveyors make a fine living from buying and selling them (see
my personal details in "What if it's stolen" above). The truth is, if it
were easy everybody would be making them, and there aren't many really fine knives out
there. Here are a few pages on this site where you can see the artistic skill and
craftsmanship that goes into investment knives, swords, and weapons:

What makes your
knives different from other makers?
Short answer: I make them.
Long answer: Every knifemaker is different. Some make only folders, some make only
tactical knives. Some forge, some hand grind. Some heat treat, some don't. There are many
beautiful, functional handmade custom knives out there, and each one displays the maker's
own individual artistic style (that is if the maker isn't just copying someone else's
work). The difference is in the whole "package," that is, what the maker as an
individual brings to the table.
Often, an enthusiastic individual will come to a Knifemaker's table at a custom knife
show, or art and craft show, and stand gawking at the beautiful finishes and glistening
steel. He sees a clean, apparently simple knife offered for $600 and gasps. After the
usual questions, some silent mental calculations about time and value (see | |
