This professional manual 3-stage knife sharpener is a game-changer for getting super sharp edges on all your knives. It offers two angle classes - 15 and 20 degrees. With separate sharpening and honing stages, it creates long - lasting double - bevel edges. The ergonomic handle fits all hands, whether you're right or left - handed. All three stages use 100% diamond abrasives. Diamonds are superior as they sharpen faster, create stronger edges, and won't detemper the knife edge. It can sharpen the entire blade length, from the tip to the bolster or handle. The Chef’sChoice AngleSelect Model 4633 elegantly styled with a compact footprint, can be used on various quality knives like kitchen, household, Santoku, sports, pocket, and serrated knives. It quickly restores 20 - degree edges on traditional European and American style knives and 15 - degree edges for Asian and modern Euro/American style knives. With precise angle control and an advanced sharpening system, it makes a super sharp, durable edge. It has slip - resistant rubber feet and is designed and assembled in the U.S.A.

Using the Chef's Choice M4633 knife sharpener is easy. First, decide whether you need a 15 - degree or 20 - degree edge for your knife. Place the knife in the appropriate slot. Hold the knife firmly by the handle and slowly draw the blade through the sharpening and honing stages, starting from the tip to the bolster. Do this a few times until you get the desired sharpness. When using, make sure the sharpener is on a flat surface as the slip - resistant rubber feet will keep it in place. Always be careful when handling sharp knives. For maintenance, keep the sharpener clean. After use, wipe it with a dry cloth. Store it in a dry place to prevent rusting. Since it uses diamond abrasives, it's quite durable, but avoid using excessive force as it may damage the sharpener or the knife.
