Holy Crap!

i worked maintenance for a tree company and besides the gawd awful state of every piece of equipment the shocking lack of safety protocols was stunning.

with the exception of one climber. he took care of his saws with a level of reverent attention. and he also had a giant scar on his left arm with a tattoo that required no explanation: saw don't care
I've used every kind of saw imaginable, skil saws jig saws scroll saws table saws, you name it. Two scared me. Chain saws, and we had a GIANT abrasive chop saw, used for cutting steel. It had a three FOOT abrasive blade. When that blade came apart (at least twice I can remember) it sounded like a plane crash, and except for the guard, would have killed the operator.
