This is what happens when you pinch your hand cutting copper tubing. Mind you, it doesn't look as bad as it did when it was gushing blood for half an hour, but it hurt plenty and embarrassed the hell out of me for making such a rookie move. Took a small brush and peroxide to it to clean it out then added neosporin and a bandage later on. Why I didn't go for my camera when I did it is beyond me. Oh yeah, the chunk of skin came completely off. I just put it back on to cover up the hole to keep the dirt out. It'll make a big scab.
