Abstract

A folding multipurpose tool including adjustable locking pliers with an over-center locking mechanism to retain the jaws in a gripping condition. The jaws of the locking pliers can be folded into the handles of the tool to produce a compact folded configuration. A latch mechanism in the tool handle retains a selected one of several folding tool bits or blades in an extended position for use and includes an abutment arrangement to prevent such a selected tool bit from being extended too far. A spring associated with a tool bit driving socket retains separate tool bits and resists inadvertent removal of an adjustment screw element of the locking pliers. Upon removal of the adjustment screw element, special bits, such as a corkscrew, can be screwed into the tool bit driving socket.
