The CRKT Slide Sharp™ is a proven simple and economical knife sharpening system* that holds your blade at the correct angle to achieve a sharp edge quickly, every time. After many years in the knife industry, Steve McCowen of Iola, Wisconsin had seen literally hundreds of knife sharpening systems, ranging from stones to expensive electric hones. The simpler devices required a good deal of skill, the more advanced systems came with mounting hardware and pages of instructions, and the electric sharpeners could grind the edge of a favorite knife to nothing in a few seconds. The Slide Sharp uses a unique system of injection-molded nylon guides to hold the knife edge at the specific angle required for optimum sharpening. A hardwood base holds a porcelain sharpening rod. Simply insert the rod in the base, slide a return spring over it, select the sharpening guide needed for your knife, and slide on the cap.
