Name: Kairouseki "Pole"
Description: While at first look it gives the impression of a Nodachi, once taken off the shreath, it is a pillar made of seastone with a pointy edge. It is roughly 1,5 meters in lenght and 7 cm's in diameter.
Since it is inside its "cane" it is easy for Fruit users to carry it around without harming themselves.
Special abilities: As a weapon made of seastone, its useful vs Fruit users, as well as extremely durable.
History: It was one of the many things the Kurojuuji Kaizoku got as a reward for Suigo's assistance against the revolutionaries.
