I accidently cut my thumb all the way to the bone with my Dremel (cutting wheel), I sawed through a little bit of bone too while i was at it No need for pictures here though because of the meat hangin, blood squirting, and bone shavings!
I sawed through the end of my thumb with a junior hacksaw a few weeks back- blade skipped on the aluminum during the 1st stroke, and went about 6~7mm into the end of my thumb, straight through the nail like butter. Didnt hurt at first, but later it ached like heck.
That was a good one, I did almost the same thing to myself when I decided to fire up my first brushless emaxx before programming the radio to the esc. It took off my desk at full tilt, taking my arm with it. Very funny, and the dent is still in the wall!
I just love typing in "accidents" into youtube, and just laughing my ass off...the boating accidents are the best!
