Irwin VISE-GRIP Fast Release Curved Jaw Locking Pliers CR 

Self-energizing lower jaw provides 3x more gripping power than traditional locking pliers with no slipping or stripping. Provides maximum torque without requiring heavy input pressure as jaw mechanism naturally grips tighter as more torque is applied to the tool. One-handed, triggerless release is 2x easier to open than traditional locking pliers. Anti-pinch, non-slip ProTouch Grips provide comfort, control, and less hand fatigue. Curved jaw puts tremendous pressure on four points of any style nut or bolt head, making it perfect for any application that requires maximum torque
