A rasp, also known as a woodworking file, is used for creating more precise shapes in wood and other timber objects. Compared to a metal file, a rasp utilizes a teeth set that is quite wide apart and is a bit deeper. This enables carvers to cut coarser and allows a chunk of surface material to be removed in one stroke.
