The Outdoor Edge Sharp-X knife sharpener is a folding, pocket-sized two-step sharpener that is ideal for shaping and maintaining a razor-sharp edge on all of your outdoor and kitchen knives. Set at a universal 22 degree angle, the coarse, tungsten carbide bits reshape a dull blade quickly, while the white Alumina-Ceramic rods are utilized to finish the blade to a razor's edge. For improved safety and stability, the Sharp-X features a folding base, rubberized TPR finger hold, and four 3M rubber foot pads.
