ABSTRACT:
A tool is provided for use in combination with a conventional claw hammer. The tool comprises an integral tool body having a sleeve for surrounding the cylindrical striker section of the hammer head. A support portion extends outwardly from the sleeve generally at right angles to the longitudinal axis of the sleeve and carries at its remote end a surface engaging curved portion for resting against the surface from which a nail is to be pulled and for acting as a fulcrum holding the hammer away from the surface to improve the direction of pull on a nail grasped by the claw of the claw hammer. The surface engaging portion at the end of the tool has an apex at one end including a sharpened claw for engaging a fully embedded nail. At the opposed end is provided an anvil surface which can be struck by the hammer to drive the apex into position to grasp a nail. The tool has two steps therefore firstly being used to grasp an embedded nail and secondly being used with the hammer head engaged into the receptacle as an additional fulcrum of the hammer.
