During the time Sokka spent training with Piandao, he crafted his sword using ore from a recently fallen meteorite. The weapon is able to cut through various metals with little to moderate effort, and it has a distinctive dark hue that can be attributed to the material from which it was forged. Sokka seemed to have bonded with it in a similar fashion as had taken place with his boomerang, having given it the nickname "space sword".
