About

KNUCKLEBUDDY® is a patent pending universal wrench extension that adds maximum leverage to your existing wrenches.

Initial proof of concept trials offered tenured mechanics to use this product for three weeks prior to purchasing. KNUCKLEBUDDY® proved to be more productive than using a second wrench that could turn or slip.
