If I had not had on chain saw gloves a few days ago, I would have had a nasty cut to my left hand. In the BLINK of an eye, it happened and I'm not even sure how it did. Cut my gloves in two places, so, would likely have been two wounds.
My neighbor recently showed me a pic of her co-worker's relative. Apparently, he caught a kickback to the face. I wish I had not looked at it. She showed me before and after surgery. (She works in an eye surgery clinic.) It was awful, I tell ya. The surgeon did an incredible job but that guy will be terribly scarred for the rest of his life.
I try to be careful but it's hard to be perfect with a saw. I even bought a new set of chainsaw gloves that with an even higher rating. Also looking into chainsaw boots. Those suckers are expensive! My steel toe military boots are probably pretty good but they are not chainsaw boots.
