Which weapon would you choose?

In a 1 on 1 duel, which weapon (No projectiles, bows, guns or futuristic weapons) would you use? Both of you have only one weapon and no armour, your enemy has the same skill set as you and you are in a sand based arena (much like the gladiator pits)

Spear.

Katana or Wakizashi probably

Bingo

I'll take Poseidon's trident from Douluo Dalu, Or the master sword, or a Lantern ring, or the infinity gauntlet.

Maybe a bo staff

@chazz85: @thekillerklok: I meant in more of a non-fiction sense.

Spear or Katana.

Those sticks Nightwing uses.

Some kind of blunt instrument. Swords take skill to use.

@humphreytt: Oh sword then.

I think an axe would be the best. If you have enough skill and aim, you could use as a projectile, or just run up and hack with it.

Katana or custom brass knuckles with bayonets weld into it.

First post nailed it on the head. Spear. Easy to use, hard to fight against.

Keysword/Green Lantern Ring/Lightsaber/Sonic Screwdriver//Doom bot.

Pilasy:La Voix d'un homme

Flail

A machete.

Wait no, a baseball bat.

Ah then I'll take a halberd, or perhaps a Tiger fork.

@curlyinsaneguy: What if the opponent has a sword or a mace?

cutlass or combat rapier

Energy Sword. Hahaha! Kidding! I meant any Japanise Sword would make us win

Probably a warhammer

@darling_luna: The deadliest weapon of all.

Flail

I don't know it just looks easy to hit someone with that :P

Butter knife

unarmed combat

I'm surprised not many people have chosen the katana given that most people on the internet love that sword.

I find it much more interesting that people are picking weapons they have obviously never trained with.

Yer most people seem to go for the more flashy looking weapons that fall apart when you start cutting.
