A wrench having an elongated handle attached to a head. A spool and rotatable member are rotatably mounted in the head. A one-way clutch drivably connects the spool with rotatable member. A cable wound around the spool extends longitudinally through the passage in the handle. When the cable is pulled out of the handle the spool is rotated. The one-way clutch drives the rotatable member which rotates without swinging the handle. A spring acting on the spool rotates the spool to wind the cable on the spool. A releasable lock interposed between the handle and the spool permits rotation of the spool in resonse to angular movement of the handle.
