When the U.S. Army"s 82nd Airborne was looking for a high-performance, purpose-designed knife for its Jumpmasters, they looked to Spyderco. A Jumpmaster oversees airborne troops as they exit an aircraft during parachute operations. If a soldier hangs up and his chute fails to deploy, the Jumpmaster needs a reliable cutting tool to quickly and safely cut the static line. Spyderco’s Jumpmaster is that tool. Its serrated Sheepfoot blade powers through webbing, rope and other fibrous materials with a vengeance. Hollow ground from H-1 steel and featuring an aggressive fully-serrated (SpyderEdge) cutting edge, the Jumpmaster"s blade is totally rust-proof and remains sharp even after prolonged use. Featuring full-tang construction for strength, it has black, Bi-Directional Textured fiberglass-reinforced-nylon (FRN) handle scales to guarantee a positive grip in the most demanding circumstances. An ambidextrous injection-molded polymer sheath allows the knife to be strapped securely to the calf for rapid access and deployment.
