Souba

The Souba is a kind of weapon which appeared in Final Fantasy VII: Advent Children. It is the main weapon of Kadaj, leader of the Sephiroth's remnants who appear in the movie. The Souba is a katana with two reinforced parallel blades, set a small distance apart from each other, which permit to trap an opponent's sword. Some of the Souba's replicas can be split into two katanas, but this feature has not been officially confirmed.
