  • Knife: Custom made for donation to a dedicated Combat Control Team professional in the 26th Special Tactics Squadron of the United States Air Force for his combat achievements, this is a presentation grade and working tactical knife, made to use and carry in the field, retiring after service to a custom made wall plaque. The PJSK Viper is one of my series of counterterrorism combat skeletonized knives, made to be extremely lightweight, as robust as possible, and with special features all around. The blade steel is 440C, my most often requested combat knife material used by special tactics and military professionals because of its tremendous corrosion resistance, high toughness, and high wear resistance. I made this blade as good as it can possibly be, with cryogenic quenching in heat treatment, followed by triple tempering with cryogenic thermal cycling for the best combination and results in chromium carbides, iron carbides, and excellent stability in use. The blade is thick, over 1/4" for high durability, with 4.5" of thin, hollow ground tanto-point cutting edge, razor keen. The blade has 2.25" of my hammerhead serrations for ripping through tough materials and a three quarters length top swage for reduced point profile and good penetration. The handle is a milled "footprint" design handle with full thickness, and all rounded, smoothed, and contoured surfaces for a comfortable grip and light weight. The knife is custom engraved.
  • Sheath: Versatility is critical and a necessary function of the professional knife ensemble. This sheath is a professional assembly, clearly, the best tactical sheath and accessory package made in the world. It's also an example of my commitment to making the finest combat tactical, and rescue knives and sheaths on the planet. It starts with double thickness coyote brown (.125") kydex (methyl acrylate and polyvinylchloride), hot-formed over an anodized aluminum welt frame of 5052 high strength corrosion resistant aluminum alloy in H32 hardness. The body and welts are secured with bead blasted and slotted tan oxide 304 stainless steel Chicago screws for the ultimate in durability with no care and no glare. The sheath is one of my reliable hybrid tension-locking models, securing the knife with tension until high strength or physical displacement of the mechanism allows removal of the knife. This usually takes about 15 pounds of pressure, but two additional spring plates in 6AL4V titanium (not shown) offer a variety of tension options. The user can choose his best tension, and the entire retention arrangement is reversible. Everything on the sheath is highly corrosion resistant, even the machine screws are all stainless steel and all titanium is anodized. The sheath can be worn in any position, even upside down when worn with the die-formed high alloy aluminum belt loops and belt straps on PALS webbing and every conceivable arrangement of combat gear. The belt loops can be located in multiple positions along the welt frame and are reversible for a variety of wear options. This spacing also allows the array of my sheath accessories to mate with and locate in multiple positions along the welts, and allows the knife to be mounted to virtually any gear in any position! The flashplate is removable for field use, and the plaque sits at home or base ready for retirement of the knife after missions and use. The plaque is ash hardwood, stained in cherry, sealed and varnished with polyurethane for longevity. The hangers are steel covered with nylon and foam rubber, attached with stainless steel screws, and the commemorative plate is engraved scarlet lacquered brass.
  • It's an honor to make knives for our nations top Special Tactics combat professionals, and both the donation from my special clients combined with my own donation is what brings this all together.

Thanks to the benefactor, R. F. for his kindness and support of our military.
