And I even refuse to play with pointy sticks...
What the heck does it mean to be a modern authority on knife/counter-knife tactics. I mean have we developed new knifing (maybe kniving is the correct term. I am neither a knifer {or a knifist} nor a grammariam {or a grammarist}) technology that we need a modern expert. I'm no counter-knifing (or counter-kniving) expert, but I think a gun is a pretty effective counter tactic in a knive fight.
