Keeps your knife at hand when you need it the most. Drawing from his experience in the 82nd Airborne, knife designer Antonio Rodriguez developed the Taco Viper® sheath to keep his knife close at hand and tethered during critical airborne missions. Made of tough woven nylon, the lightweight sheath features velcro to keep the sheath open for easy access, and a snap for secure closure. The sheath also comes with a carabiner and elastic cord to keep the knife attached during unstable conditions.
