Abstract
A sliding jaw wrench with a movable lower jaw and a stationary upper jaw. The upper jaw is attached to an elongated shank and the bottom portion of the shank is threaded. An opening in the lower jaw piece allows the lower jaw to slide around the threaded shank. A handle with internal threading is screwed onto the threaded portion of the elongated shank thereby pushing up on the lower jaw piece and causing the jaw opening of the wrench to tighten.
