Vise

A vise, spelled vice in British English, is a mechanical apparatus used to secure an object so that work can be performed on it. A vise has two parallel jaws, one fixed and one movable, drawn together or apart by a screw and lever; the jaws are often flat, though they may carry grooves, be shaped to the workpiece, or be custom made. The standard woodworking vise, mounted to a workbench to hold wood steady while it is worked, is its own separately covered specific type; an engineer's vise, also called a metalworking vise or machinist's vise, clamps metal instead of wood. A vise grip is a related but different tool: it is not a vise at all but a pair of lever-actuated locking pliers.
