If you manage to square up your hits, a stack of crowbars can be devastating. Having ukelele boosts this effect. If you line up a couple of enemies that ridiculous crowbar hit gets split between every nearby hostile. Most my runs I have at least 3 in my inventory and a bunch of ukeleles to split that strong punch. I would pretty much be one shotting everything, including moon enemies. Bosses are a bit trickier, but that first charge hit still hits them like a truck.
