Long Sword

The Long Sword is Kirito's main default sword, which replaced the Black Iron Great Sword, presumably during the latter part of the Fairy Dance Arc or after it.

This sword was forged by Lisbeth using a rare metal found in Jötunheimr and is one of her best masterpieces.

The Long Sword appearance is similar to Kirito's Dark Repulser in Sword Art Online, which was forged by Lisbeth as well.
