Spyderco Delica 4 Red G-10 HAP40/SUS410 Black Exclusive - Combination Edge/Plain Edge. Specially manufactured for St. Nick's Knife Factory, this limited-edition Exclusive Spyderco Delica® 4 boasts a unique combination of features not found on any other expression of this model.
The blade of this distinctive knife is a three-layer laminate comprised of HAP40 and SUS410 steels. HAP40 is a high-speed tool steel produced by the powder metallurgy process—an advanced manufacturing method that reduces alloy migration within the steel to yield an extremely fine, uniform carbide structure. The generous amounts of tungsten, molybdenum, vanadium, and cobalt in HAP40's alloy mix give it exceptional toughness and high abrasion resistance—key qualities of a superior blade steel. The high-performance HAP40 core that forms the cutting Edge of this blade is flanked by layers of SUS410 martensitic stainless steel to increase its structural strength. It is then coated with a handsome black titanium carbonitride (TiCN) coating.
Not to be outdone, the handle of this remarkable knife features full stainless steel liners, a stainless steel backspacer, and textured red G-10 scales. To complement the blade's stealthy TiCN coating, the liners, lock bar, four-position pocket clip, and all the handle's other metal hardware also feature non-reflective black coating.
