Abstract
The locking pliers comprises a first handle connected to a first jaw. A second handle and second jaw are pivotably connected to the first handle and first jaw such that movement of the first handle relative to the second handle causes the jaws to open and close. A mechanism is provided to lock the jaws relative to one another and apply a clamping or gripping force on a workpiece positioned between the jaws. A release mechanism is provided to unlock the pliers that is independent of the locking operation.
