Gouge refers to one of several types of cutting tools, in addition to its meaning as a verb (the action of cutting or scooping with or as with a gouge) and its slang meaning (to cheat, defraud, swindle) and, rarely, as a noun meanng a swindler (gouger).
In Antiquity
In archeology, a gouge is a bifacial or unifacial stone tool with a chisel-like working edge used for woodworking purposes; some may also have been used to remove marrow from bones. Gouges are generally triangular in shape, with the working edge -- characteristically steep-angled -- appearing at the wide base of the triangle. The opposite edge, at the point of the triangle, was the hafted end; the tool itself was generally hafted at right angles to the handle.
Modern tools
A modern gouge is a tool similar to a chisel except its blade edge is not flat, but instead is curved or angled in cross-section. The modern version is generally hafted inline, the blade and handle typically having the same long axis. If the angle of the plane of the blade is on the outer surface of the curve the gouge is called an 'incannel' gouge, otherwise it is known as an 'outcannel' gouge. Gouges with angled rather than curved blades are often called 'V-gouges' or 'vee-parting tools'. Variations include 'crank-neck' gouges, 'spoon-bent' gouges, etc.
