Abstract
A pair of locking pliers includes a first assembly defining a first handle and a first jaw, a second handle, and a second jaw rotatably coupled to the first assembly and the second handle. The second handle is movable relative to the first handle to move the second jaw relative to the first jaw. An improved lock and release mechanism has a first setting wherein the second jaw is freely movable relative to the first jaw, a second setting wherein the second jaw locks at a preset distance from the first jaw when the second handle is moved toward the first handle, and a third setting wherein the second jaw unlocks when the second handle is moved toward the first handle.
