Abstract
The wrench comprises a frame having a head and a fixed jaw on the head. A movable jaw is movably carried by the head and movable toward and away from the fixed jaw. The frame, the head and the jaw are composed of stacked plates. Two of the plates of the frame respectively define frame ledges and two of the plates of the movable jaw respectively define jaw ledges. The jaw ledges respectively overlap the frame ledges so that the movable jaw captures the frame, thus preventing the frame from spreading or tending to delaminate under heavy load.
