Wado Ichimonji

This katana carries deep personal meaning for Roronoa Zoro. It was crafted by the Wano swordsmith Shimotsuki Kouzaburou and long served as a cherished heirloom of his line, ranking among the 21 Great Grade swords. When its previous keeper Kuina died, Zoro requested the blade from her father Koushirou, who handed it over to him.

A Shinogi Zukuri katana, Wado Ichimonji wears a snow-white grip of ito wrapped over gray same'gawa in a diamond weave, with a rounded golden guard and a straight suguha temper line. Its edge splits into a deep black inner groove and a gleaming white outer edge, the slightly curving blade tapering to a keen point, while a plain white sheath completes its air of restrained elegance. Tashigi judged it a magnificent katana of the highest caliber. The weapon proves extraordinarily tough even without Haki: it survived a strike from Mihawk's Yoru that shattered Zoro's two lesser swords, and he used it to cut through Mr. 1's steel body with Shishi Sonson. After the timeskip his greater strength and Armament Haki amplify its power, letting him carve through Pica's giant stone form and even wound Kaidou.

The blade's line of ownership runs from Kouzaburou to Koushirou, then Kuina, and finally Roronoa Zoro. Zoro typically clenches it in his mouth as the third sword of his Three Sword Style. He refuses to ever sell or surrender it, brushing off Ipponmatsu's attempts to buy it in Loguetown, an encounter that also drew Tashigi's vow to take it from him. Because Kouzaburou forged both this sword and Enma, Sukiyaki noted that wielding Wado Ichimonji helped Zoro adapt quickly to Enma during his Wano training.
