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. Archaeology, archeology, or archæology (from Greek grc ἀρχαιολογία archaiologia – grc ἀρχαῖος archaīos In archaeology a biface is a two-sided Stone tool, manufactured through a process of Lithic reduction, that displays flake scars on both sides In Archeology, a uniface is a specific type of stone tool that has been flaked on one surface only A stone tool is in the most general sense any Tool made of stone. Gouges are generally triangular in shape, with the working edge—characteristically steep-angled—appearing at the wide base of the triangle. A triangle is one of the basic Shapes of Geometry: a Polygon with three corners or vertices and three sides or edges which are Line opposite edge, at the point of the triangle, was the hafted end; the tool itself was generally hafted at right angles to the handle.
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. A broader definition of a tool is an entity used to interface between two or more domains that facilitates more effective action of one domain upon the other A chisel is a Tool with a characteristically shaped Cutting edge (such that wood chisels have lent part of their name to a particular grind) of blade on 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. Gouges are used in wood working and arts. For example, a violin luthier will use a gouge to carve the violin, a craftsmen may use it to scoop out wood for a project, or an artist may produce a piece of art by cutting some bits out of a sheet of linoleum (see also Linocut). Linoleum is a Floor covering made from solidified Linseed oil (linoxyn in combination with Wood flour or cork dust over a Burlap or Canvas Linocut is a Printmaking technique a variant of Woodcut in which a sheet of Linoleum (sometimes mounted on a wooden block is used for the relief surface

In U. S. Navy jargon, gouge is the essential piece of information; the heart of the matter; or outstanding test-preparation material (such as an old test copy). A person who is tired of hearing all the extraneous information surrounding a problem might exclaim "Just give me the gouge!"
