Was using a 5" craftsman DA sander years ago to make a slingshot, I think I was 10. Touched the sander to the wood in my left hand, before I knew what happened the wood was across the shop and I had sanded through the back of my thumb where it meets the hand with 80 grit.
Couple years back i used a 12" miter saw to cut a pice of material down for the scrap pile. Bench was cluttered, didn't care about the cut so put the stick down and cut. Blade caught and slammed the crooked material against the fnce, trapping 2 fingers. Next day my middle finger was so purple and swollen I thought it would pop, turns out I smashed the end of the bone off. More or less healed back in place, but every now and then I'll wack the tip on something and it almost brings me to my knees.
Renovating in the house last summer, balanced the recip saw with long demo blade on the stepladder. Turned around, bumped the ladder and the saw fell raking the blade down my leg. Nice roadrash, and all I had to clean it was a bottle of hand sanitizer. The hair is starting to grow back now.
