The serrations on a bread knife make it a great tool for three other jobs in the kitchen: 1. Cutting fruits and vegetables with soft skins. The serrated teeth on a bread knife make it easier to cut tomatoes, mangos, and more. 2. Leveling and shaping cakes. If you’re interested in baking more than just bread loaves, a bread knife will help. 3. Preparing fruits and vegetables with thick rinds. Melons and squashes come apart easily with a bread knife. Trim away the outside rind, and then you have easy access to the succulent inner flesh.
