The VISE-GRIP curved jaw locking pliers from Irwin (Phoenix, AZ) feature a self-energizing lower jaw. According to the company, the jaw tightens for maximum grip as torque is applied to the tool. They are available in two core models: Fast Release, with a one-handed, triggerless release and anti-pinch, non-slip ProTouch™ Grips; and Original, with a classic trigger release. The Fast Release model has a no-trigger release, offers one-handed operation, and includes anti-pinch, non-slip ProTouch Grips for comfort, leverage, and a reduction in vibration and hand fatigue.
