SELF-RETRACTING BLADE - This safety knife's spring-activated blade retracts when lifted from the cutting surface, minimizing accidents and unwanted cuts. The powerful stainless steel return spring ensures tension and elasticity are maintained. RAZOR SHARP BLADE - Our knife is preloaded with an SKB-2 Safety Blade made from high-quality carbon tool steel for unparalleled sharpness and superior edge retention. Simply flip the blade 180 degrees to switch from right to left-handed preference. STURDY PLASTIC HANDLE - This slim, lightweight knife has a high-impact ABS plastic handle. A recessed blade slide prevents accidental blade exposure in a holster or pocket. The stainless steel channel keeps the blade securely in place during use.
