I've had several bad cuts.
--Had an older Spyderco Jess horn and was flicking it open while walking. I thought I had it fully open, but it was at a 90 degree angle and made contact with my leg. Straight through my jeans like they weren't there and 2.5-3 inches into my quad (doctors estimates). What hurt the most was when the doc had to "explore the wound".
--I was throwing my Spec-Plus SP-1 at a tree, which I had done successfully hundreds of times prior, and not paying enough attention. It didn't stick, bounced off the tree and nailed me in the left shin. Hobbled me good for about a week. That is an ugly scar, but fading.
--I was fire-side one night with a S+W Bushhog stuck in the ground after splitting some wood. I decided to take a load off, sat down on the ground, and put the bottom of my hand/wrist area into the blade. I was very drunk so it bled like crazy. It's about a 2 incher.
--Had one of my BM-42s reground by Tom Krien with a double edge. I knew it was a bad idea, but went with it anyhow. I thought I'd practice flipping with my left hand, and it didn't go too great for me. I'd say this was to the bone for sure.
--Worst was a Sog Desert Dagger. Had taken the top part of the sheath off, so the knife could be worn IWB. Unfortunately that left nothing at all for retention. (This was one of the later sheaths, with the Sog logo in the edge of the plastic/kydex). Anyhow, I put it on a wall mounted speaker for a moment and it started to fall. The knife was still near mint, so I didn't want it to hit the floor. I tried to stop it but all I got was sheath, and the knife was sort of flung out. My reaction was to grab for the knife with my other hand, and that was a mistake. It cut about 180 degrees around the inside of my left index finger right at the base. I had to go under the knife to have things reconnected. They cut me up the side of my finger to gain access, so it's a double whammy of sorts. They said the nerves would grow back, but it's still partially numb and there's pain occationally to this day.
--I also have a 2 incher running from my right ring-finger finger-nail to the middle nuckle. This was the first, and I should have learned from it probably. I was still a wee yoot, and we thought it would be fun to "sword fight" with kitchen knives. I remember telling the paramedics that we were breaking a Transformer and a piece of plastic cut me. -I don't think they bought it.
--There's several more, including a Coldsteel Peacekeeper to the forearm, and a small fillet missing from my thumb form a hatchet of all things. All I can say is that I used to drink heavily and was pretty careless with my sharp stuff, obviously. Sadly, this is nothing compared to the firearm mishaps I've made and witnessed. But no one ever got hit, thank God. -One of these days I'll get some pictures of my scars and try and post em.
