Description:
The wrench portion is a rack and pawl quick adjust nut and pipe combination wrench. The swinging auxiliary handle advances a screwdriver blade, operates the wire cutter, and tightens the grip of the movable wrench jaws. The fixed head has a nail claw and hammer head.

Produced as TRITT'S LAMBERT PATENT in black and nickel finishes. The adjustment mechanism in the movable jaw is slightly different than the one shown in the patent drawing.
