Shears
Definition:
(n.) A cutting instrument.
(n.) An instrument consisting of two blades, commonly with bevel edges, connected by a pivot, and working on both sides of the material to be cut, -- used for cutting cloth and other substances.
(n.) A similar instrument the blades of which are extensions of a curved spring, -- used for shearing sheep or skins.
(n.) A shearing machine; a blade, or a set of blades, working against a resisting edge.
(n.) Anything in the form of shears.
(n.) A pair of wings.

(n.) The bedpiece of a machine tool, upon which a table or slide rest is secured; as, the shears of a lathe or planer. See Illust. under Lathe.
