ABSTRACT:
A ratchet puller for nails and staples in accordance with this invention includes a ratchet lever or bar having a ratchet mechanism at one end with a tool mounting stud extending from the ratchet mechanism, and a pry tool for mounting thereon which includes a claw portion having a wedge slot for receiving the shanks of nails, spikes and similar items to be pried out of a piece of wood or other structure they are embedded in and which may include a pointed tip or stab to hook under the bight portion of staples and similar items for prying out of whatever they are embedded in.
