Most knife "fights" involve two guys, one knife and one loser I'd bet. Knife/gun? Obvious answer and winner. If I am going to carry a knife it might as well be one I could use to defend myself with right? If you are not going to carry it, it won't help defend you. If I am taking a blade and looking for a fight? I think I would want oh say a katana, to keep it Busse I will say AK47. Also, it would be hard for your average unarmed crook to hurt you as bad you would hurt them armed with a knife.

If your too fat to run you won't fight as well as you could. Not to say fat guys can't kick butt <img src="/ubbthreads/images/graemlins/tongue.gif" alt="" />.
