Shusui

Name: Shuusui (Clear Autumn Water)

Owner: Samurai Ryuuma → Roronoa Zoro

Price: Unknown

One Of the 21 O Wazamono or '21 Great Edges' of the world. It was Samurai Ryuuma's meitou, who appeared as an zombie on Thriller Bark that had Brook's shadow. Zoro took the sword from Ryuuma after he defeated him. Zoro has commented that Shuusui's greatest attribute is its hardness; saying that even if a dinosaur were to step on it the blade wouldn't bend.

Just as Sandai Kitetsu turned out to be a "problem child", Zoro describes Shuusui as having a "temper". It is designed to increase the damage potential of the user, however Zoro soon discovers the real problem about this blade; while Yubashiri was extremely light Shuusui is very heavy.
