Well it depends, If everyone in the arena was getting one, you'd want something heavy enough for the 5 year olds to not be able to pick up.
Let's face it, if you're wearing a cup, and they have teeth missing, you are pretty much impervious to attack. any weapon would give them advantage. If only I got a weapon, I'd take a good old chainsaw. perhaps a shotgun. then, club with it after you run out of ammo/petrol.
Guitar related? something metal plated and spiky, perhaps taken from the gayest picture in the world
