A brilliantly engineered tool.

Yes, you have been using the old school second wrench gimmick. KNUCKLEBUDDY is eliminating that non-tool second wrench used as a leverage bar.

We know what you mean. The second wrench tends to turn and slip. That can get frustrating. KNUCKLEBUDDY locks on to all combo wrenches with no problem / no slipping. Plus, when a part is in the way you can use it to engage a wrench from a 30 degree angle. A second wrench cannot. Own the tool engineered for the job. We have not had one dissatisfied customer. This tool works. Mechanics tell us they love it. One stated; I'll never double wrench again. Another customer posted "I got mine. It's no hype; I'm happy with my purchase." The price is reasonable and affordable. You get a quality built tool for your dollar. Why is it that we rarely use pliers? One day people will say; "we never use a second wrench" KNUCKLEBUDDY is now the tool of choice. It out performs and is replacing the second wrench methodology.

Never work alone again.
