  • Knife: The Aldebaran is a great tactical knife that has found great use in combat, counterterrorism, and PSD (Principal Security Detail) use. It's an aggressive, tough, large swept tanto blade, and in this custom piece commissioned by a great client, he wanted it brought to a high finish with premium steel and striking and beautiful materials and style. The blade I made in CPM154CM high molybdenum, high chromium martensitic stainless steel. This is modern powder metal technology steel, created as a finely powdered mass fused into a solid bar with no segregation or density variation of the alloy components. I've employed deep cryogenic treatment in quenching at -325°F with additional deep thermal cycling and compression in triple tempering at -325°F for the ultimate in high wear resistance with high toughness this steel offers. This extensive and detailed heat treating process insures the maximum carbide precipitation, maximum transformation of martensite, and quite simply, makes this steel the very best it can possibly be. This is a beautiful blade, with a smooth, even, appearance and no visible grain, only possible with powder metal technology tool steels. The grind is large and deep, creating a very keen edge that is well supported with a thick spine. The tanto edge has three cutting areas, the first at the point and the slightly curved grind in front of the dividing line (yokote), the second a straight length of razor thin edge, and the third a two-inch run of my aggressive hammerhead serrations. The knife has a two third's length top swage to reduce point profile without sacrificing strength, and the fully tapered tang has full vine filework for handmade distinction. The handle is a very curvaceous form, adapting well to the hand in forward or reverse grip; it's thick and strong, and comfortable without being too heavy for such a large knife. The knife is bolstered with zero-care 304 high nickel, high chromium austenitic stainless steel, and the bolsters are contoured and rounded for comfort and good grip. The dovetailed bolsters lock a pair of beautiful, rich, dark blue Dumortierite gemstone handle scales to the tang, a seamless fit. Dumortierite is an aluminum boro-silicate mineral with a high hardness (7 on the Mohs scale) and great toughness and is one of the most durable and timeless blue minerals on earth. Simply put, this stone will outlast me, the owner, his many generations to come, and the knife by countless centuries! This is the nature of hard, tough stone, and one of the reasons I love to use it. The color in this dumortierite ranges from deep dark blue to a lighter sky blue, with bits of other minerals, shiny hematite, and quartz throughout. This particular stone comes from Namibia, Africa. It's polished and smooth, and inviting to hold. The knife is aggressive and strong in the hand, proving that beauty can be authoritative and respected.
  • Sheath: To sheath this special knife, I created a deep layered sheath with a high back, to expose the handle for easy unsheathing, and protect the wearer at the belt line. I used 9-10 oz. leather shoulder, and hand-carved large inlay areas in the front, back, and in the belt loop. I inlaid the sheath with a dozen pieces of mocha brown shark skin, carefully orienting the grain for visual interest. This is a tough skin, in some very thick leather, and I hand-stitched the sheath with black polyester, with the belt loop getting double row stitching for extra durability and strength. The sheath body is dyed black, and all of it is sealed with acrylic for permanence.
  • A strikingly beautiful tactical knife form in premium materials and finish that was an honor to make.

Thanks, S.!
