IRWIN Vise-Grip Groove Joint Pliers have an all-purpose jaw that can grip onto flat, round, hex and square work pieces. The multi-groove ratcheting system has twice the number of groove positions compared to traditional groove joint pliers. Press-n-slide button adjusts the jaws 2x faster than traditional groove joint pliers. Anti-pinch non-slip ProTouch grips provide control, comfort, and less hand fatigue.
