Vise-Grip ®
From WikiPedalia
A type of locking pliers. It has a toggle link mechanism in one leg, and an adjusting thumbscrew in one of the legs. Vise-Grips are operated much the same as quick-release mechanisms.
This is a tool of last resort for removing nuts or bolts whose heads are so badly damaged that the proper wrench will not fit them. Vise-grips should not be used on un-damaged fasteners, because their serrated jaws will damage the part they are used on.
