Give your kitchen knives a professional sharpening right at home with the Precision Edge 2-stage knife sharpener from Wusthof, which requires nothing but a few easy strokes to keep all your Wusthof knives sharp. It features hard carbide steel blades for a coarse sharpening stage and fine ceramic rods for the honing stage. Simply place the Precision Edge on a flat work surface, hold the grip handle with one hand, and insert the knife blade fully into the slot at a 90-degree angle to the sharpener and pull back a few times to sharpen. After setting the knife’s edge with the carbide side, use the unit’s ceramic side to nicely finish the edge. It measures 9 by 1-1/2 by 3-1/2 inches, and it’s weighted for added safety.
