Spyderco Stretch Burnt Orange HAP40
Tracing its history back to 1983 and Spyderco’s first purpose-designed folding hunting knife, the C03 Hunter™ model, the Stretch Lightweight is a highly evolved folder optimized for processing game. 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 knife’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-strength back lock mechanism, fiberglass-reinforced-nylon (FRN) scales with Bi-Directional Texturing™, a Trademark Round Hole™ for reliable one-handed opening, and a four-position clip that offers all possible carry configurations. To make the HAP40 Stretch Lightweight even more unique, its tough FRN handle is injection molded in a distinctive burnt-orange-colored hue.
