A new and simplified version of the revolutionary three-stage Tech Edge sharpening system, this revolutionary knife sharpener provides fast, easy, and professional results. The unit sharpens and hones any knife brand, and its quick and easy Diamond Fingers technology ensures a sharp blade with just a few swipes. Simply pull the blade down and back through the eight diamond-coated Ozitech fingers. The sharpener perfectly sets the edge bevels and professionally hones the edge at the same time. So simple, it eliminates the error and guesswork associated with traditional sharpeners. The unit's clam shell unfolds in seconds to provide a strong handle and safety guards. Folded, the shell provides compact, pocketsize storage measuring 1 by 3-1/2 by 4-1/2 inches--perfect for on-the-go chefs, home cooks, and outdoor enthusiasts.
