Typically a hand tool, it consists of a generally tapered rectangular, round, or half-round sectioned bar of case hardened steel with distinct, individually cut teeth.
[1] Rasps come in a variety of shapes—rectangular, round, and half-round—and vary in coarseness from finest, "cabinet", to most aggressive, "wood".
[2] Farriers, for example, commonly use rasps to remove excess wall from a horse's hoof.
They are also used in woodworking for rapidly removing material and are easier to control than a drawknife.
The rough surfaces they leave may be smoothed with finer tools, such as single- or double-cut files.
