The Satan Sabre (サタンサーベル Satan Sāberu) is a weapon created for use by the Century Kings. Though Bilgenia took it, after Shadow Moon awoke, he easily reclaimed the weapon and took it as his own. He used it during the final battle against Kamen Rider Black, but was defeated. While trying to stop the Creation King from destroying the Earth, Black rides Road Sector and summons the Satan Sabre with his own will and throws it into the king. The Satan Sabre was vaporized by Kotaro, who throws it into the sky as a final token of respect to his brother.
