GOUGE (adopted from the Fr. gouge, derived from the Late Lat. gubia or gulbia, in Ducange gulbium, an implement ad hortum excolendum, and also instrumenlum ferreum in usu fabrorum; according to the New English Dictionary the word is probably of Celtic origin, gylf, a beak, appearing in Welsh, and gilb, a boring tool, in Cornish), a tool of the chisel type with a curved blade, used for scooping a groove or channel in wood, stone, etc. (see TOOL). A similar instrument is used in surgery for operations involving the excision of portions of bone. " Gouge " is also used as the name of a bookbinder's tool, for impressing a curved line on the leather, and for the line so impressed. In mining, a " gouge " is the layer of soft rock or earth sometimes found in each side of a vein of coal or ore, which the miner can scoop out with his pick, and thus attack the vein more easily from the side. The verb " to gouge " is used in the sense of scooping or forcing out.
