LoggerHead Tools

Loggerhead Tools was founded by Dan Brown, an inventor, consultant, and entrepreneur who holds 30 U.S. utility patents. Working for 30 years helping bring products to market, he was met with a unique challenge when his son wanted to use pliers to change components on their lawn mower. Dan knew that doing so would strip the nuts and bolts. "I thought, wouldn't it be great to have a tool that performs like a wrench but can grip like pliers?" His solution was the Bionic Wrench, based on the open and close action of a camera shutter. The Bionic Wrench fully surrounds a nut or bolt, applying a strong grip, while allowing the user to comfortably use tremendous force. The Bionic Grip offers the same patented grip technology with an open-head design. The Compact Screwdriver is adjustable to reach difficult spots while delivering enough torque to get the job done. He combined features of all three in an ever-useful multitool, offering out-of-the-toolbox innovation for the job at hand.
