Rasp
Template:Short description Template:About Template:More citations needed
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.<ref name="lye 12" >Template:Citation</ref>
Uses
Rasps come in a variety of shapes—rectangular, round, and half-round—and vary in coarseness, from finest, "cabinet", to most coarse, "wood".<ref>Template:Cite book</ref> 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.
Rasps are used in shaping alabaster. Saws and chisels are used to rough out alabaster work.
Machine-made rasps have uniformly stamped teeth. They often leave deeper marks as rows of teeth follow each other exactly, and will require a subsequent smoothing step.<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> A hand-cut rasp is still a premium tool for carving work, as the slight variation in tooth spacing avoids this 'tramline' effect and so they are still available, at a price.
