Using your Chef's Choice Manual Knife Sharpener Model 463 is super easy. First, make sure your knife is clean. Then, hold the sharpener firmly on a stable surface. Take your knife and gently pull it through the first slot of the two - stage sharpening system a few times. This starts the process of getting your blade sharp. After that, move on to the second slot and repeat the pulling motion to refine the edge. When using, always keep your fingers away from the sharpening slots to avoid any injuries. Also, don't use excessive force as it might damage the sharpener or the knife. To maintain your sharpener, clean it regularly with a soft, dry cloth to remove any metal shavings or debris. Store it in a dry place to prevent rust or other damage. With proper use and care, your sharpener will keep your knives in great shape for years.
