I've also broke quite a few knives using them to pry things. Or open bottles. Or open cans. Or throwing them.
However, these are the ones that I broke that don't consider 'abuse'.
Broke my first boy scout knife whittling one of those wood race cars. Tip snapped while "drilling". I was being careful, but <shrug>. My dad wouldn't let me replace it. I saved up and got a Buck. Broke the Buck scraping paint off an old chair for a wood shop project. (ok, I know that a knife isn't a paint scraper...still...for those nooks and cranies it was a good tool for the job and I wasn't allowed to play with paint thinner anymore

)
I broke a mystery machete hacking blackberry bushes. Don't know what happened, I swung, and pulled back half a machete.
I broke the tip off a
throwing knife by throwing it. Found the tip stuck in the tree.
Broke about 1/2" of tip off a kabar learning how to baton and hit at a bad angle. I was pretty pissed. My technique is much better now, but if I was cold and tired and in a survival situation, I could imagine doing the same thing again and again.
The reason Busse stays in business is because of people like me.

I Have yet to break one of them, and it's not for lack of trying.
