Orvera is referring to my Final Fantasy Advent Children Buster Sword. Its only 6 1/2 feet tall, so yeah, close to 12 haha. But yeah, i built it for the pure reason of wanting to make it possible with foamsmithing. Theres a pic of it all put together on the WTF Weapons topic, none of it taken apart yet cause i'm lazy and i dont have it at school with me.
As for Sokka's sword, its nothing more than a common chinese Jian made with space metal. its basically what anyone makes when they have a double sided longsword with a stabby. anything beyond that is just detail which can be done with plastidip. no one would likely notice Sokka's sword placed next to any other dag longsword
