Well its been an interesting 12 hours...

[Lt.]

Most highly informed people (as in, survived attacks by knives and been in countless street fights) I've spoken to highly recommend Kali and its various offshoots for knife defense

I train with a pretty brutal shotokan dojo and we do, in fact, mix a lot of escrima (kali) into our stuff.

but we focus on severing the bicep, slashing/stabbing the neck and belly, and generally hurting the attacker very, very badly. there really isnt a safe way to defend against a knife, its mostly an issue of counter-attacking.

for that matter you dont even need a knife to counter attack.
If you are thinking about "knife defense" chances are you have already been stabbed, or soon will be. now its just an issue of bloodying the guy before he bloodies you, which can be done with your fist/boot.

bad luck man.

keep the distance agains knifes! = run! knife is so dangerous. you have to be a well trained warrior to engage a fight against a knife man, if your not , dont try it.
dont need to fight.. if you REALLY want to fight, come back later with a better preparation (weapons) to find the one who robbed you

Knowing Bob, don, I somewhat doubt he is looking for revenge
