From my friend a former federal agent:
If you’re ever in a knife fight, and you get to the other guy, yell “You’re cut! You’re cut!”
Adrenalized, he might not realize it till you tell him, and once informed, he might quit fighting.
Let me know how it works out.
I’ll try to remember this for the next time I’m in a knife fight. By the way, about all I know about knife fighting is that it is a good idea to take a gun to one.
Better to have the Bigger knife
