    Abstract: A multi-function tool is disclosed which provides prying as well as leverage-enhanced gripping capability. By combining the lever arm of a prying bar with the gripping capability of gripping pliers, this multi-function tool provides leverage-enhanced gripping and leveraged-forced movement of objects. The lever action of the prying bar can be applied via the gripping pliers, thereby allowing a user to exert more force via the gripping pliers than is possible by using gripping pliers alone. In some embodiments, the prying bar is a crowbar, and the gripping pliers are vice grips. In preferred embodiments, the prying bar and the gripping pliers are welded together.
