Black Iron Great Sword

The «Black Iron Great Sword» is the unnamed NPC purchased sword used by Kirito in his initial run through «ALfheim Online». He purchases this extremely large and heavy sword in Sylph territory after appraising his lightweight starting-gear sword as lousy.

In appearance, this black great sword is almost as tall as Kirito's Spriggan form, nearly touching the ground when sheathed along his backside. Its immense weight is just right for Kirito as he is 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 both Demonic Sword Gram and Holy Sword Excaliber. After Kirito's fight with Fairy King Oberron, Kirito discards his «Black Iron Great Sword», noting that its job was completed.

However in the last episode of the anime, Kirito still carries it in his ALO inventory.
