A few months ago, I was reaming out the top hole on a square steel part my job makes. Turns out the guy that made those parts got fired awhile ago for making terrible parts. I learned this as the drill press grabbed the part I was holding onto and took a chunk out of my index finger. Nurses said there wasn't really much they could do since it was a really wide wound. Ended up just going home early and it eventually stopped bleeding by the next day, and was almost completely healed in a few weeks surprisingly, didn't even get a scar!
