Sokka's sword was a weapon crafted by the young Water Tribe warrior during his swordsmanship training with Piandao. It was forged using ore from a recently fallen meteorite, and Sokka later referred to it affectionately as his space sword due to the origin of its material. The weapon is able to cut through various metals with little to moderate effort and has a distinctive dark hue that can be attributed to the material from which it was forged. Sokka bonded with his sword, much like he bonded with his boomerang.
At the start of his training under Piandao, Sokka hardly knew the proper way to hold a sword. However, he had a great natural talent and progressed quickly, being able to beat the butler, Fat, after a single day. Three days into his apprenticeship, Sokka and Piandao began working on making his sword. Sokka decided to make it out of a meteorite he and his friends had encountered earlier, and spent days forging the sword. After receiving this, he blew his Fire Nation cover deliberately, prompting Piandao to instigate a duel to the death, albeit fake, as a final test to make sure that Sokka had learned the necessary skills. During this fight, Sokka showed how much he had learned about the way of the sword in just a few days, showing great resourcefulness and the ability to recognize and exploit every advantage. Piandao eventually beat him, but was greatly impressed by his progress and said that Sokka had the potential to one day be an even greater master than him.
Sokka left Piandao's tutelage to help Aang on his quest to save the world from Ozai and started putting his new skills to use shortly thereafter. Sokka had no qualms about using his sword in untraditional ways, such as to haul supplies on the end of it, or poke people with the scabbard. However, he prized the sword very much, second probably only to his boomerang, his oldest weapon, given to him by his father Hakoda. He grew fearful when Toph used it as collateral in one of her scams without his permission. The warrior later used the sword in combat during the invasion of the Fire Nation, as well as in a friendly swordbending duel against Prince Zuko, which he lost.
When Sozin's Comet arrived, Sokka, along with Toph and Suki, went to stop the Fire Nation airship fleet from burning the Earth Kingdom to the ground. After commandeering and crashing one of the airships into the rest of the fleet, Sokka and Toph were thrown off during their attempted escape, but the former managed to halt their fall by burying his sword into the airship's outer hull as a grapple hook. Stranded and about to be attacked by firebenders, Sokka sacrificed both his boomerang and his sword, throwing them at the planks supporting their opponents. This prevented their deaths just long enough for Suki to rescue them with the last airship, but neither the sword nor the boomerang came back, plummeting to the ground of the Wulong Forest. Made for 1:12 figures but will likely need scaling before printing.
