My first knife was an old case two blade non-locking folder. I think I spent more time trying to sharpen that thing than I ever did actually using it. Used to play mumbledee peg with it until I stuck it in my brother's foot. Then Dad took it and I never saw it again, and didn't own another knife for a couple years(till I learned some respect for such things I reckon).

I've done more damage to myself with an x-acto blade than I will ever do with a real knife.
