But i must say that the paisaw is just as badass against dretches as a knife would be; For once, i dont think the paisaw is easy to aim at that dretch, and you wouldn't have one arm free to fend off the dretch.
In my opinion, figting dretches with a painsaw is much like trying to kill flies with a chainsaw.
so... ..conclusion reached: the painsaw is WAY more badass against dretches than the knife will ever be, and just badass enough against tyrants.
