The sword seems to simply be a larger version of a regular longsword. It has a dark green hilt and seems to lack a sheath. Due to fighting with it for over a hundred years, it has become old and dull.
In Dorry's hands, the sword is quite a dangerous weapon. It can easily cut through the bodies of the dinosaurs on Little Garden. However, it had become too fragile to withstand Dorry's assault on the island eater.
Hakoku (覇国,Hakoku?, literally meaning "Warrior Nation"): Putting all of their strength into it, Dorry and Brogy each call upon Elbaf's "warrior code", and slash their weapons at the ocean, creating two compressed air beams (Dorry's is blue, while Brogy's is red) that will slice through anything in their path, even the ocean itself. However, the amount of power needed for this attack proved to be too much for the giants' rusty weapons, so both this sword and Brogy's axe shattered. In the Viz Manga, this is called Hakoku Sovereignty.
