Ever see Princess Mononoke? *not sure whether it was a dagger or knife but the two are similar so it doesn't matter*

And not all KNIVES are used by cowards. If you throw knives accurately, you're skilled and have acute aim. If you attack your enemies head on, it forces you to be swift and cunning.
Just because someone attacks another before they can see means that that person needs to be more aware and plus, who wants to give your opponent a chance to kill you?
