A wrench is held in a steel case body that provides added leverage to the wrench shank. The body has a clock spring that is wound, to be released for moving a hammer into contact with the wrench shank to loosen stubborn nuts or the like. A ratchet and pawl provides a convenient means to wind the spring, and a release button releases the spring so the hammer can "tap" the wrench.
