Kitchen knives are essential tools used for food preparation. They come in various shapes and sizes, each designed for specific tasks, such as chopping, slicing, and dicing. Common types include the chef's knife, paring knife, and serrated knife, each serving a unique purpose in the kitchen. Proper care and maintenance of kitchen knives are important for safety and longevity. Regular sharpening keeps the blades effective, while washing by hand and storing them safely can prevent damage. Using a cutting board also helps protect both the knife and the surface being used, ensuring a more efficient cooking experience.
