Space Sword

Sokka's Sword, affectionately referred to as Space Sword, is a weapon used by the Sokka in the animated television series Avatar: The Last Airbender.

Appearance
Sokka's sword is a jian straight sword, with a blade approximately twenty-seven and a half inches long. The blade is black from the origin of the material. The hilt is a golden irregular pentagram, and the handle is a brown wood with a round gold pommel that is etched with the symbol of the White Lotus.

Its sheath is dark brown with a gold inlay, with the tip adorned by a gold filigree symbol of the White Lotus.

Powers and Abilities
Due to Sokka's involvement in the creation of the sword, the sword was made specifically to fit his fighting style and structure. While there is no mystical, spiritual, or supernatural connection between Sokka and the sword, the sword is "attuned" to him and is easy for him to use.

Due to the sword's material, it is extremely strong and durable, capable of cutting through steel.

History
In an attempt to make himself more useful, Sokka sought training in swordsmanship by the Fire Nation swordsman and bladesmith Piandao, under an alias to ensure the Fire Nation government did not catch him. After progressing quickly in his training, Piandao tasked Sokka with forging his own sword. Sokka opted to forge the blade out of a meteorite that he had witnessed crash nearby a few days prior, to which Piandao agreed. The two worked together and forged the blade, which Piandao displayed to him. However, Sokka felt unworthy of the blade and his master's training, and revealed his true identity. Piandao challenged Sokka to a duel, and though he won, he was impressed by Sokka's resourcefulness and skill with his blade. Piandao revealed himself to not be loyal to the Fire Nation government, and let Sokka leave with the sword.

Sokka utilized the blade throughout his quest with Avatar Aang, and grew to prize the sword very much, and was even fearful when his friend Toph used it as collateral without permission. He later used the sword in the invasion of the Fire Nation, which his side lost. Despite the failure, he continued to hone his skills, training with fellow swordsman and former-enemy-turned-ally Zuko.

Later during the arrival of Sozin's Comet, Sokka brought the Space Sword on his mission to stop the Fire Nation fleet from destroying the Earth Kingdom. After commandeering and crashing one of the airships into the rest of the fleet, Sokka and Toph attempt to escape off the top, but are thrown off. Sokka uses the Space Sword to stab into the side of the ship, grabbing Toph and saving her. However, with Fire Nation soldiers incoming, Sokka was forced to throw the sword at the platforms beneath them to save them both until their ally Suki arrived to help them. The sword fell into the ground of the Wulong Forest below, and was never found.

Trivia

 * Sokka's sword and sheath, as well as Piandao's sword and sheath, are designed based upon real swords owned by Sifu Kisu. Kisu was the martial arts consultant for the show's creators and was also the character reference for Piandao.
 * The concept of a sword being made out of a meteorite was derived from the ancient Mongolian legend of Timur.
