Abstract: An improved locking wrench is provided. The improved locking wrench includes a stationary upper handle which includes a fixed upper jaw, and a lower jaw pivotally connected to said upper handle so that said lower jaw is in opposition to and pivotally movable towards and away from said upper jaw. A lower operating handle having a distal end pivotally is connected to said lower jaw and movable between closed and opened positions which responsively pivotally moves said lower jaw towards and away from said upper jaw. A toggle lever is pivotally coupled at one end to said lower operating handle and has an opposite end coupled operatively to said upper handle.
