ABSTRACT:
A large capacity locking pliers includes a body, a fixed jaw, a movable jaw, and an over-center toggle linkage secured between the movable jaw and the body to lock the movable jaw in position with respect to the fixed jaw. The jaws define respective working surfaces, and each of the working surfaces defines an end portion, an intermediate portion, and a concave inner portion. The concave inner portion of the fixed jaw extends over an arc .alpha. of at least 45.degree. and the concave inner portion of the movable jaw extends over an arc .beta. of at least 80.degree.. These concave inner portions are concentric when the movable jaws move to a selected open position to grip a large cylindrical workpiece. The fixed and movable jaws are asymmetrical in order to facilitate fabrication and finishing of the completed pliers.
