    In woodworking, rasps are used for rapidly removing wood from curved surfaces. They remove less wood than a drawknife, so they are easier to control. Even though rasps leave very coarse finishes, the cut-away areas can be easily smoothed with finer tools, such as files.

   There are several types and shapes of rasps. There is a half round, round and flat. The several types of rasps are bastard, cabinet and wood (finest to coarsest). All these varieties can be used to make different shapes.
