A tool similiar to a wratchet but longer and with a stationary head used to loosen / tighten high torque nuts and bolts or other such fasteners.
I used a breaker bar to loosen the lug nuts on the pinto

I big f*cking metal bar used to apply buttloads of torque onto stubborn/siezed nuts and bolts via a rachet socket. Saves your ass on many applications.
This bolt won't turn. Git the breaker bar.
