Tony Swatton, the veteran armorer and master blacksmith who previously recreated the Dark Knight's Batarangs and Captain America's shield on his web series Man at Arms, is back to craft a replica of Thor's hammer Mjolnir.
Apparently lacking uru, Swatton and his crew instead use materials like chromoly steel, bronze and other Midgard materials to forge the mighty weapon, which weighs 20 pounds hollow and will be 200 pounds when filled.
