Common types of kitchen knives include the chef's knife, paring knife, and serrated knife, each designed for specific tasks. The blade of a kitchen knife can be made from different materials, such as stainless steel or carbon steel, which affect its sharpness and durability. Proper care, including regular sharpening and safe storage, is essential to maintain the knife's effectiveness and longevity in the kitchen.
