The Santoryu three-pack set includes replicas of the three swords that make up Roronoa Zoro's Santoryu - Three Sword Style - fighting configuration: the Sandai Kitetsu, the Wado Ichimonji, and the Shusui. Santoryu is Zoro's signature fighting style in One Piece, using all three swords simultaneously with two held in his hands and one in his mouth. Having all three swords together as a set creates the complete Santoryu display - the three color statements of red Sandai Kitetsu, white Wado Ichimonji, and black Shusui together represent the full visual identity of Zoro's fighting style. A four-pack set additionally includes the Yubashiri, which Zoro carried for a period of the story as his third sword before acquiring the Shusui. All swords in the sets are made from 1045 carbon steel with full-tang construction and individually fitted fittings appropriate to each sword's design.
