These are great little knives that are an essential for both home cooks and professionals. Knife Care (Stainless Steel) Although this knife is made from semi stainless steel we do still encourage our customers to keep their knives as dry and clean as possible. NO DISHWASHER - the high heat will ruin the wooden handle. Wash and dry by hand using regular dish soap and warm water using a none abrasive sponge or cloth. Ensure the knife is dry before being put away for storage and ensure the edge of the knife is protected to avoid any unnecessary dulling. Avoid Bones, Frozen foods, nuts and hard candies or anything other than fruits, vegetables and proteins.
