I like to got it good spring of 2020. Cutting a bunch of brush out of the way to get to get to a blown down tree, got too hot and sweaty and careless, cut into a Chinese privet hedge trunk that was about four inches diameter. Got about two thirds of the way through the thing, it twisted and pinched, the saw kicked back right into my left knee. Didn't cut deep enough to go get sewn up but bled a bunch for a few minutes. Cut was ground full of sawdust, bar oil, cotton fabric, blood and chewed hide. Almost made it to the kneecap. Left a three inch long scar diagonally across my knee as a reminder to slow down and be careful. An eighth of inch deeper and it would have been bone time and I can't imagine how much pain that would have been. And how long to heal up.
