Irwin Industrial Tools introduces the Vise-Grip Quick Adjusting Wrench. In an attempt to revolutionize the traditional adjustable wrench, Irwin has replaced the thumbwheel with a lever that adjusts the jaw two times faster with a single motion. Also, because the jaw locks securely into place, the Vise-Grip will not strip nuts, bolts or fasteners. The grooved internal jaw slides forward manually for quick, one-handed sizing and locks in place for leverage and repeated use. Vise-Grip is available in metric and SAE versions.
