I have hit the blade many time over the years, never drew blood. Guess I am just a tough skinned old Fart. Fell 12 ft. out of a tree the other day and after a few minutes laying there looking up at the tree I decided I was still alive, slowly got up to make sure nothing was broken and went back to work. Few bruises, sore spots, but everything is still working. Life is good,,, so far.
