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 works like a chainsaw, wherein small blades or teeth circulate around its spine, the only difference though is that it also uses heat to further the effectiveness of the sword and to heighten its sharpness. 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 simplified version exists which unfolds and is shaped more like a baton with a blade extending from the top which is available to the Black Knights' standard knightmare frame, Akatsuki.
