dad,
i ever tried this experiment with friends from different martial arts/those who claim to be good in street fights. i hold a marker to stimulate a knife, they can do whatever they want to disarmed me. after the experiment i come to this conclusion, there is no way you can win an armed personal. i saw marker marks on the neck of my fren face and etc before they can use their so call polish technique to disarm me. btw i din even bother to kick or punch them, merely aim at slicing and hacking. you might argue i know martial art so maybe its more effective in my hand, but i am untrained in weapon, as good as nothing.
i still going to stick to RUN RUN RUN.
