Revolving Blade Sword

The Revolving Blade Sword (廻転刃刀, Katen Yaibatou) is a superheated rotating blade. It is capable of slashing through most knightmares with the exception of Anya's Mordred which took a direct hit and didn't get a scratch. It was originally used exclusively by the Four Holy Swords and Kyoshiro Tohdoh in their Burai Kai and Gekka. After the remnants of the Japanese Liberation Front were assimilated into the Black Knights, it became standard equipment on all of the Black Knights commander Knightmare models which were the Akatsuki Command Model Zikisan with the exception of other custom swords like Kyoshiro Tohdoh's Zangetsu which uses a Brake Sword. A lesser version exists which unfolds, available to the other knightmare model, Akatsuki.
