The Claymore (クレイモア Kureimoa?) is the weapon of choice for Saïx. They are large weapons that "open" in some fashion, becoming wider and gaining some sort of supplementary blade, when Saïx enters his berserk state. Most of his weapons' names have something to do with the moon or the night. His signature weapon is called the Lunatic.
