Serrated knives come in many shapes and sizes and offer a vast array of uses throughout food preparation. They are especially useful on foods that are tough on the outside but soft on the inside as they can cut through a tough exterior without crushing what is inside. Serrated blades can have a wavy, scalloped, or saw-like blade. This type of knife also requires less frequent sharpening as they cut better than plain edge blades when dull. However, serrated knives often require specialized sharpeners to hone the blade and some may not be able to be sharpened.
Some common examples of serrated knives include steak knives, bread knives or tomato knives. Slicers and utility knives can also have a serrated blade.
