The Black Iron Great Sword refers to Kirito's unnamed weapon of choice in «ALfheim Online» during the Fairy Dance Arc. It was later replaced by Kirito's unnamed black long sword. Leafa speculated that the sword was made for an Imp or Gnome character due to its size, and was amazed that Kirito, whose avatar seemed to have a speed-build, chose such a heavy sword. Its immense weight was just right for Kirito, as he was able to even block arrows while wielding it with one hand. Even though the sword is nothing special in appearance or power, in the hands of Kirito it is able to match against the «Demonic Sword Gram».
