once upon a time, a man developed this idea in his head to make it easier for people to tighten and loosen bolts that were torqued down more than the normal person can recreate...thus the impact wrench was born and ever since then people have been using it. Use this saying, "if at first you don't succeed, find an easier way!" this applies very well here...rather than still having to exert a nice bit of force on a breaker bar
sorry fellas, but i'd rather reach for the impact and be done quicker...
