Your hand might not break, but it still really painful. Breaking a stack of 6 with a knife hand, my wrist would usually be sore and bruised up the next day. It would take a week or so for full mobility.

I still think most people in the world wouldn't be able to break 2 pavers with no spacers. :)

Interesting. I was doing this kind of stuff in high school, never had such problems and I don't know personally anyone that did (and I used to know a few dozen people practicing various styles of karate). In any case wrist pain suggests a very bad strike technique or weak wrist muscles.
