LOGGERHEAD Tools offers a new type of hand tool that combines the mechanical advantages of an adjustable wrench with the simple features of a pair of pliers. The hybrid is called the 8-in. Bionic Wrench. The new product uses six hardened-steel jaws to automatically size and grip 16 U.S. and metric-sized nuts and bolts. Just a one-handed squeeze distributes equal force on all sides of the work.
