Vice-Grip
Also known as locking pliers or moles, Irwin's Original Vice-Grip locking instruments, with the classic release of the guard, provide maximum blocking for the exceptional performance that professional professionals depend on. The jaw curve of the lute jaw allows the user to put enormous pressure on the four points of any type of nut or bolt head and to help release bolts that may otherwise be locked! To lock the clamp on a Vice-Grip locking wrench, first grasp it with the pliers and adjust the jaw by rotating the screw at the end of the grip.
