The mechanist uses a small stationary holding device called the mechanist’s bench vise to grip the work securely when performing bench operations. It is essential for holding work pieces when filing, sawing, and clipping. The jaws are made of cast iron and have removable faces of hardened tool steel. A vise consists of a fixed jaw, a movable jaw, a screw, a nut fastened in the fixed jaw, and the handle by which the screw is turned to position the movable jaw.

The lining jaws can be made of paper, leather, wood, brass, copper, or lead. A smooth face is inserted to prevent marring the surface of certain work pieces. In addition to the typical vise described here, there are many other varieties and sizes.
