  • Knife: A fine primary edged weapon, the Mercury Magnum pattern was originally designed by and made for a west coast law enforcement SWAT team member as his tactical daily knife for weapon, tool, and utility carry. The tanto blade style is very aggressive, with a steeply angled point that is made for piercing, with a half length top swage to reduce the spine thickness without sacrificing strength. This knife has a blade made of dependable, corrosion resistant, and tough 440C high chromium martensitic stainless tool steel, hollow ground and nicely contoured, bead blasted for a low care, low glare finish, tempered to 58 HRC. While the blade is not as long as many of my full combat knives, it has an advantage in being lightweight with a lower profile for more comfortable carry. This one has 1.5" of tight serrations for help with stubborn tasks, while leaving plenty of edge length for cutting. I've put a very sharp single bevel edge on the knife for a good start in its life. The handle is canted slightly downward for the wrist comfort, and the quillons are substantial on both ends of the handle. It locks well between the fingers, and with no filework, the handle will stay clean and neat. The knife is bolstered with austenitic high chromium, high nickel 304 stainless steel, solidly pinned to the fully tapered tang and dovetailed to bed the handle scales. The scales are blue/black G10 fiberglass-reinforced epoxy laminate, an extremely durable, long-lasting synthetic material with nice visual appeal. The bead blasting of the handle gives it great texture to aid in gripping, and the knife can be held in either traditional or defensive grip positions. The thumb rise has the additional width of the front bolster pair for bearing down. The rear bolster has a .250" through-tang lanyard hole for extra security. The balance point of the knife is exactly at the union of the front bolster and handle scales, where the forefinger rests. With a good belly and about 3.4" between the quillons, the handle is comfortable for small to medium hand sizes. If you have an extra large hand, it may be too tight for you. You can size your hand on a special page on this site.
  • Sheath: I've made one of my fine locking, waterproof tactical models for this knife, probably the best sheath style made anywhere. While most makers use a single thickness kydex (.060"), I use kydex that is (.125"), twice that thick for strength, durability, stability, and longevity. The kydex is hot-formed over a 5052H32 corrosion resistant, high strength aluminum welt frame, secured with nickel plated steel Chicago screws and waterproof cement. The sheath has all stainless steel locking components in 302, 304, and 316 austenitic stainless steel for low-care, high corrosion resistance, and durability while positively locking the knife in the sheath. Even the machine screws and reinforcements are stainless steel. 1.75" wide belt loops are die-formed in high strength aluminum, and are reversible for versatile wear in any position.
  • A great medium-sized knife for tactical, light combat, defensive, and utility carry and use.

Thanks, B. M.!
