Some of them, yes, are friggin' razors... but I cut my finger off years ago when I was working in a deli. "Hmmm salami doesn't usually have that much blood... Oh. Well that's not good." I'm pretty sure those were my exact words. If not, it was something very like it.
Meat, though, grows back, so you can't tell it happened by casual observation. If you look close, you can see the nail grows in weird. Nerves, on the other hand, do not grow back. Some idiot left an open straight razor on the counter in the shop one night, and while searching for something in the dark, I found that instead. I knew it was a bad cut because it hurt, which meant it cut all the way down past the bit that had been cut off. Not wanting to search around in the dark for the first aid kit (for understandable reasons, I hope), I took my pants off, wrapped it tightly, and waited for morning, by which time the wound had closed and scabbed over, so I washed it off and taped it up. now I have a somewhat different fingerprint.
