This limited edition Sprint Run of the Stretch Lightweight combines all the benefits of this field-proven design with a laminated blade crafted from HAP40 and SUS410 steels. This knifeÂ’s full-flat-ground blade features a central core of HAP40, a high-speed tool steel produced by the powder metallurgy process. Containing generous amounts of tungsten, molybdenum, vanadium, and cobalt, it possesses exceptional toughness and high abrasion resistance—key qualities of a superior blade steel. The high-performance working layer of the blade is sandwiched between layers of SUS410, a martensitic stainless steel that gives the blade increased strength and corrosion resistance. This three-layer structure creates an extraordinary combination of properties that ensure exceptional cutting performance, edge retention, and structural strength. All the other elements of this unique knife are the defining features of the Stretch Lightweight—skeletonized stainless steel liners, a high-strengt
