thats a tought one but i think sam would win. snake would knock him out and spend half an hour looking for his dog tags. by then sam wakes up grabs snakes pistol and bang!
katana all the way man, faster, stronger, more balanced, broadswords are hard to wield and take more actual strength, plus on tv it said that the katana was the best type of sword ever developed...also its japanese so thats cool too
