Re: techniquies in street fights
I read a report a fews years back where somebody compiled a list of knife attacks and ran a statistical analysis on the circumstances. The most common attack, by far, was an overhead strick (ice pick attack). The most common target/wound area was the back of the neck.
Two things struck me about this study (if you'll pardon the pun): (1) the overhead attack is a lot like shomen uchi, and (2) never turn your back on somebody with a knife!
