Abstract
An improved cam for use in a rope gripping device features a concave cam working surface. Gear-like teeth, each having a flat top are placed perpendicular to the rope inside the concave cam working surface. The cutting force is reduced, and the grip strength is increased. An integral safety lock can be set in either the open or closed position.
