Kaku's Swords

The pair of swords used by Kaku are just a pair of katanas with wooden hilts and wooden sheaths. Oddly enough, when Kaku was using them in his half giraffe form, the swords themselves became noticeably larger. This was never addressed as either being a deliberate change or simply done for affect.

[edit] Abilities

Used in conjunction with Rankyaku, Kaku can create the powerful Four Swords Style. The strength of this style is further augmented by Kaku consuming the Devil Fruit, Ushi Ushi no Mi, Model: Giraffe. These swords are also strong enough to clash with Roronoa Zoro's Three Swords Style without breaking.
