By a sword....no. By a goat carcass, yes.
In no particular order -
I have removed a chunk from a finger with a first-gen Delica spyderedge while on the phone with a girlfriend, plyaing with the knife as we talked, that required quick-stop (stiptic powder) to stop bleeding.
Last year I was doing some full-out dynamic cutting drills on a goat carcass and hit it with a good number three, from stong hip to weak shoulder. However, my blade presentation was pretty crappy and the blade was not riding way out in front of the hand - long story short, I must have hit a rib and then I got to clean the inside of the finger with a dish sponge and Ajax, a truly special feeling, prior to pouring a pint of hydrogen peroxide into the wound, another special moment. After I made a wad of paper towel and my fist as one as we drove nearly an hour to the nearest emergency room.
The ER folks were really genuinely exciteable as I showed up with what was pretty obviously a knife wound, carrying a blade and pretty keyed up. The doc, upon explanation, told me goats are filthy and replete with neat stuff like Botulysm, which I knew and explained the Ajax and peroxide. He told me those items kill living tissue, to which I made a delicate inquiry whether said nasties are better dead along with a few skin cells or alive and thriving?
The next day my friends and I figured out a better splint/ protective padding and I resumed training - why waste a good week?
However, the doozie has to be when I was screwing around with friends in college and hit the hinge side of a door frame instead of the non-hinge side, as well as the window with the wires running thru it. Glass exploded, my arm was all the way thru, cold from elbow down and I got to see what tendon, muscle and fat looks like while still encased (more or less) inside my arm. Sorta like a diorama really.
It took a few moments of extendo-time to process thru "duct tape and peroxide are not going to fix that" and "hmm, so that's what that looks like...." and finally happened upon "oh, f()ck me...." I have all sorts of neat scars from that from pinkie to bicep.
And finally, the most irritating, I got bit by my dog on Thanksgiving last year in front of the entire family after dinner, on a freshly shampooed white area rug, the better to highlight the blood trail. The ER in town kept me there in a room for an hour and a half, refused to bring me a margarita or gin and tonic, and sent someone around when i called for a nurse and told her to bring me some Xylacaine in a syringe, a needle and thread, forceps and a few betadine wipes. The wife was unhappy as I told her to pay attention as she would be doing this next time.....
There are dozens of minor cuts and such, dropping a Mad Dog Bear Cat with wet hands and hearing it go "tink" as it bonked my shin bone, other stupid incidents with balisongs, etc.
