I first stumbled across 'Man at Arms' when he created an amazing Orcish Battleaxe from Skyrim. Man at Arms is the work of Tony Swatton, a Hollywood weapon maker and a genuine proper Blacksmith who likes to make video game/comic book weapons in his spare time. In the above video he attempts to create the most realistic rendition of the Master Sword from Zelda ever made. Spoiler: he succeeds.
Apparently the Master Sword was one of the most requested weapons ever, which is understandable. It's definitely the weapon I most wanted to see created. The final result is pretty spectacular — especially the Fruit Ninja style demonstration at the end.
