Dragonbane is an Akaviri katana which is especially effective against dragons. Magical lightning flickers across the blade and helps make it effective against other types of enemies as well.
Dragonbane was a weapon of the Blades, perhaps dating back to the time of the Dragonguard. When the Blades were forced to seal off and abandon their ancient stronghold in Skyrim, Sky Haven Temple, the blade was left within. In 4E 201, the Last Dragonborn unsealed the temple and claimed the blade.
