Background
Loggerhead Tools was founded by Chicago inventor Dan Brown, creator of the bionic wrench principle. All of their wrenches and tools are made in the United States, and have lifetime guarantees. Manufacturing is done by Penn United Technologies Inc of Cabot Pennsylvania. Multipurpose tools are a relatively new field for loggerhead, beginning with the Immix tools in 2006 and continuing with the Bit Dr in 2008.
