Serrated knives are kitchen tools designed with a saw-like edge, featuring small, sharp teeth along the blade. This unique design allows them to cut through tough surfaces easily, making them ideal for slicing bread, tomatoes, and other foods with a hard exterior and soft interior. The serrated edge grips the food as it cuts, reducing the pressure needed and preventing squishing. Commonly found in many kitchens, these knives come in various sizes and styles, including the popular bread knife and steak knife, each tailored for specific cutting tasks.
