In Deadliest Warrior, some weapons appear during testing or the simulation that doesn't appear in the official weapons list of the warrior.
Cannons
Due to being a siege weapon requiring an entire crew, early cannons are only tested to compare with another siege weapon that was commonly used. Anti personal cannon is only tested against another similar cannon. [Pirates, Cortés, Pancho Villa]
Bayonet
Many warriors in the show have bayonets but are untested, possibly because the other enemy has a bayonet also and there would be no edge against each other. Instead, another melee weapon is used. [Washington, Napoleon, Musketeer]
Rajput Warriors
Twin Hooks
In a short video when two rajput opened a sack full of rajputana weapons their where a pair of twin hooks in it but it was not shown in list or in the simulation ,probably because the rajputs in the deadliest warrior where known to use a very different arsenal then any of the warriors and twin hooks where already used in arsenal of shaolin monks.
Gladiator
Pugio
In the episode, the Gladiator killed another gladiator by cutting his throat with the Pugio dagger. This weapon is more used for finishing off an enemy than actual combat. This knife has also been used by Roman Centurions.
Viking
Bow and Arrow
The episode showed Vikings hunting with bows and using fire arrows to burn houses.
Ninja
Makibishi Caltrop
Caltrops appeared in the testing but were not used due to no lethality.

A sword commonly found near the Mediteranean sea. Although not native to Greece, some Spartans did use this larger hacking sword. This sword is in the videogame as the Spartan's weapon.
Pirate
Musket
Some scenes showing pirates raiding a ship had some pirates using muskets. This was rare as muskets were more expensive than pistols and blunderbusses and the close range fighting of being on a ship would make them unwielding.
Cannon
The pirate cannons were not tested since they were not introduced on the show and might have been too powerful against a knight.
Knight
Flanged Mace
During the scenes of fighting between two Knight armies, one of the Knights was using a Flanged Mace. This Mace would be used in the video game.

Meteor Hammer
In the simulation, this was the first weapon used in the fight against the Maori as well as in a dramatization showing the Monks fighting off bandits. It acts similarly to the whipchain.
Wind and Fire Wheels
Some scenes of testing shows these weapons used as melee weapons and projectiles. Because the Maori had no projectiles, this weapon was not used as it would give the monk an unfair advantage.
Yakuza
Katana
A Katana or a similar sword appeared at testing and the beginning of the fight but not used at all. The Aftermath mentions that using the Katana in a gangster fashion is dishonorable, and that it would actully be a hinderance do to making the user a big target.

Another weapon shown off on the weapons table, probably discarded because of the need for stealth to be effective. It was later the Short Range weapon of the CIA.

One scene showing the Nazis in a fight had one of them throw a Model 24 grenade. This was replaced by the bouncing betty.

Revolver
A revolver was shown being used by one of the experts. Since the Cartel didn't have a signature pistol, the revolver wasn't used in the fight.
