1) Avoid a knife fight at all costs. Nothing good can come from it (except, hopefully, surviving).
2) Be like Nathan Bedford Forrest. "The firstest with the mostest."
3) If your adversary is armed, "defang the snake."
"Those who live by the sword are probably pretty f***ing good at it."
"Instructions for a successful gunfight: Front Sight, Press Trigger, repeat
as necessary." - B. Braxton
