Abstract
A pulling tool for pulling nails, screws, rivets, pegs, or other protrusions includes a jaw which may be opened to receive the head of the protrusion. The jaw is then at least partially closed against the protrusion, and when the handle of the tool is pulled, the jaw is both urged shut and also away from the surface from which the protrusion extends. Thus, as the protrusion is pulled, its shaft is also more tightly grasped, which helps to pull the protrusion from the surface without stripping off its head/cap. The pulling tool can be provided as a part of a hammer, crowbar, or other conventional tool.
