Rasp is a type of hand tool used for shaping and smoothing wood, metal, or other materials. It features a rough surface with raised teeth that help remove material quickly. Rasp tools come in various shapes and sizes, allowing for detailed work in tight spaces or larger areas. Rasps are commonly used in woodworking and metalworking, often alongside other tools like files and sanders. They are particularly useful for creating curves and contours in projects. The technique of using a rasp requires careful control to achieve the desired finish without damaging the material.
