A rasp is a coarse form of file used for shaping wood, metal, or other material. 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. A narrow, pointed tang is common at one end, to which a handle may be fitted.
