I've been running a chainsaw since1973 . Back then there were no chaps . that started to change in the late 70s. After a career of logging, falling timber and pre commercial tree thinning and Arborists work . I've never cut myself like the OP did . Thank God !! But, I have nailed my chaps and pads a few times . Those few times could have been life threatening as I often worked very remote and alone. Or high up a tree.
I still wear chaps. Its just the thing to do ! And I'm a professional.
Been waiting for mine and yes I am very lucky, I have never used them and when I was younger cut many cords of wood, just recent I was trying to start a saw and got a small bandage injury, had the saw started it would have looked like your injury I am sure. I lost control when the pull cord abruptly stopped when pulled. I was trying to start the saw after replacing the fuel system. Thanks! For sharing I am sure I would have broken down and worked on the wood before the chaps arrived as I got a notice today the shipment was delayed. Good thing I read this this afternoon. Thank you! I will be waiting.
