Dual broadswords

Dual Dao Swords are a type of metal weapon commonly used by Zuko. It can be used also as a single-edge sword and it is called broadswords too. This swords are first seen and used when Prince Zuko hides behind the mask of the Blue Spirit in the episode The Blue Spirit. He used the weapon to defend Aang and recue him from Pohuai Stronghold, a Fire Nation fortress in Western Earth Kingdom. He used it also for threaten Aang to escape. Zuko use sometimes the Dual Dao Swords when he want people don't know that he is a Firebender. In other episodes Zuko returns to be the Blue Spirit and use the swords, for example, Lake Laogai (Episode). In Zuko Alone he used his sowrds to fight Gow and his gang and taught Lee some techniques with this weapon, saying: "Two halves of a single weapon. Don't think of them as separate, because they're not. They're just two different parts of the same whole."

When Zuko enfrented his father Ozai in the Day of Black Sun, he took his swords as a method of defense, since at that time he could not use Firebending due to the solar eclipse.
