A serrated knife is a type of kitchen knife characterized by its saw-like edge, which features small, sharp teeth. This design allows the knife to cut through tough surfaces without crushing the food inside. Serrated knives are particularly effective for slicing items like bread, tomatoes, and other soft fruits, as they can easily grip and cut through the outer layer while preserving the interior. These knives come in various sizes and styles, with the most common being the bread knife. Serrated knives are often made from stainless steel, which helps maintain sharpness and resist rust. Proper care, including regular sharpening and safe storage, can extend the life of a serrated knife.
