Locking Pliers

Locking pliers, Mole grips (Mole wrench) or Vise-Grips are pliers that can be locked into position, using an over-center action. One side of the handle includes a bolt that is used to adjust the spacing of the jaws, the other side of the handle (especially in larger models) often includes a lever to push the two sides of the handles apart to unlock the pliers. "Mole" and "Vise-Grip" are trade names of different brands of locking pliers.

Locking pliers are available in many different configurations, such as needle-nose locking pliers, locking wrenches, locking clamps and various shapes to fix metal parts for welding. They also come in many sizes. Leatherman manufactures a multitool, the Leatherman Crunch, which includes locking pliers instead of regular pliers, and which folds together to the size of other multitools.
