Sabatier EdgeKeeper Knives feature a sheath with innovated technology that is designed to automatically sharpen the blade with each use. The EdgeKeeper protective sheath contains a built-in mechanism that hones the blade before and after each use, maintaining a blade's razor-sharp edge. The blade is made from high-carbon steel that lends strength, sharpness, and durability. The 5-inch Santoku knife features oval indentations that prevent food from sticking to the blade. This multi-purpose knife excels at precision cuts and chopping due to its shorter length and flat cutting edge. Knives are not dishwasher safe. Hand-wash with warm water and a mild detergent; rinse and dry immediately.
