I cut my fingertip off, twice, while on the job. First time was on a commercial Hobart meat slicer, took a peice off about the size of a dime! :x I had to go to the ER, when I couldn't stop the bleeding (I waited 6 hours, though! I'm not fond of hospitals
). They had to use those big nitrate match stick thingies to get it to stop.
The next time was with a regular, albeit very sharp, carving knive. I was scrapping roast beef, had like 50 lbs to do, just let my mind wander for a moment. I cut thru the beef, then thru my fingernail, thru the finger & into the cutting board!
Yikes! A little 'finger medallion', complete with sliver of fingernail, also about the size of a dime. No doctor this time, it quit on its own, but even after 10 years I have a funny looking scare and my finger tip isn't shaped like it was.
Another good one was on a can. Man, tin can lids leave ragged cuts. I'd have just let it go but it bled for hours. When my (now ex-) wife got home and saw the blood she freaked out, musta thought it was a drive by shooting!
That one actually needed a few stitches (and ironically I did that at home).
Innumerable burns of various degrees. I don't count those, though! 8)
BTW, Lesson learned: when the guys on the Food Network curl their fingers under when cutting, it's not just cause it looks cool!
