Abstract
A hand tool having a first handle with a front end and a blade end including a hollow frame and a sliding jaw both mounted on the front end thereof. The handle also has a core pin and a regulating screw rotatably mounted on the core pin, both located within the hollow frame. A second handle has a front end and a fixed jaw located at the front end thereof. A pivotal joint pin pivotally connects the first and second handles together with said jaws generally facing each other so that the handles are movable between an open and closed position, and the hand tool is usable as pliers. Locking means lock the handles in the closed position, so that the hollow frame is usable as a hammer head. Also, in the locked position, the sliding jaw is operatively connected to the regulating screw so that rotation of the regulating screw moves the sliding jaw with respect to the fixed jaw, whereby the hand tool is usable as a monkey wrench in the closed position.
