This elite Sprint Run edition of the best-selling Endura 4 Lightweight showcases a three-layer laminate blade with a high-performance V-Toku2 tool steel core. Renowned for its toughness at high hardness, V-Toku2 is a Japanese steel made with Swedish iron ore enriched with tungsten, vanadium, and chromium. To further enhance its strength and provide greater corrosion resistance, the V-Toku2 core of this blade is sandwiched between outer layers of SUS410 stainless steel. The layered construction is evident when the full-flat-ground blade is examined closely, as the transition between the core and outer layers is clearly visible just above the blade's cutting edge. Because V-Toku2 is a true tool steel, it is susceptible to corrosion and must be maintained properly.

All other features of this remarkable knife are consistent with the standard version of the Endura 4 Lightweight, including skeletonized stainless steel handle liners, a stout back lock mechanism, and a four-position pocket clip. Its fiberglass-reinforced-nylon (FRN) handle is also injection molded in a distinctive blue-gray hue that is the signature color of this elite Sprint Run series of knives.
