I remember seeing a training video
Of a US Marine, demonstarting how to win a #knife fight.
It was excellent!
The Marine was a real expert in knife fights.
Step one, the assailant pulls the knife on you.
Step two. You turn around 180 degrees, showing your back to the guy with a knife.
Step three (this is where you win). You sprint as fast as possible away from the guy with a knife.
