The stupidest knife related almost injury was while watching "V for Vendatta".
I have that swiss bayonet that looks like the knives in the movie and I tried the fancy finger flip he did. It came down like a heat seeking missle headed straight for my crotch and I had to do a total dive out of the way to keep from neutering myself.
I use one of those for a thrower, and I once dropped it tip first onto my Big toe. Luckily it was a little blunted from thousands of throws, but it bruised the toe badly and ensured I never did that with bare feet again.
