Wado Ichimonji is Roronoa Zoro's most personally significant blade in One Piece, originally belonging to his childhood friend and rival Kuina. After her death, Zoro vowed to carry her sword alongside his own as a tribute to their shared dream. Eiichiro Oda distinguished it visually with a pure white lacquered saya and a clean, elegant aesthetic to contrast Zoro's other, more aggressive blades. In replica form, that white lacquer finish is typically applied over a wooden saya core and polished to a smooth gloss, making Wado Ichimonji one of the most visually distinctive and symbolically loaded collector pieces in the entire One Piece sword lineup.
