Let's see...
I've cut the tip off my thumb sharpening a machete when I was 12 and my dog ate it. Stabbed a stockman straight through my foot playing mumbledy peg. Stabbed an old timer cave bear into my friend's foot playing stretch.
I was cutting a branch off the tree in the front yard once with my Ontario marine combat knife and somehow it firmly stuck me right in the sternum. My ol lady was talking to the neighbor lady in the front yard at the time.
I was whittling one time watching the super bowl and whittled a long, deep cut into my thumb that took lots of stitches to close. ER doc had to report it as a knife wound and told them I was not intoxicated (when I clearly was).
A person who shall remain nameless was doing something stupid in a fit of rage. I reached in to grab the knife and almost lost the tip of my other thumb. The cut went right through the nail, took many stitches.
I tried to "hacky sack" my Rinaldi LEO when I dropped it so it wouldn't hit the floor tip down. It cut a chunk out of the top of my foot and still hit tip down and bent the tip.
I've stabbed several knives right through leather sheaths (once very recently). I once cut right into a school book slicing an apple on it.
I had a Spyderco harpy on a long cord with a monkey fist on the end. I would hold the monkey fist in my hand and whip the cord around my hand a couple of times until the knife wound up in my hand and would flick open. I used to do it flawlessly all the time, and it was pretty cool until I flung the knife into the side of my wife's head one night when we were walking. Thank the good lord it hadn't opened and didn't hurt her at all.
I once dropped the folder I was carrying on the concrete and kicked it no less than twice trying to pick it up. I had just bought it.
All of this stuff was extremely embarrassing to me. I am sure there are more stories I don't remember, or tried hard to forget. The only good thing is I have learned a lot of lessons.
