<p>A reversible ratchet wrench handle in which the actuator for the direction reversing mechanism is located close to the portion of the handle that is grasped by the user. This permits the user to operate the actuator with the thumb of the hand holding the handle whereby changing the direction of operation of the wrench is a one handed rather than a two handed operation. Locating the actuator near the hand grip portion of the handle also removes it from the head of the handle, the usual location, and this allows the head to be made thinner for better access to narrow places. The actuator for the direction reversing mechanism is a switch button that is movable back and forth axially of the wrench handle and this kind of movement insures more positive action.</p> |
