Name: Nibai Ikusabo (Twofold Battle staff)
Type: Bo staff
Other Parts: It can be split up in two seperate segments.
Appearance: A metal stick that's about 1.8m (5.9 ft) long.
Material: Nibai is made from a metallic mineral that contains low quantities of seastone within it's chemical componants. It gives the weapon incredibly high density and heat resistance, but the concentration of sea stone is far too low to strongly affect Devil Fruit users if they somehow came into long contact with it. They might feel a bit out of shape at best. It's a rare mineral that can only be molded by using certain melting techniques, though it is unknown to most people and not considered valuable.
