Yubashiri was one of the fifty Ryo Wazamono grade (called Skillful Grade in the Viz edition) swords. Roronoa Zoro obtained this sword for free from a sword shop owner. The sword was a family heirloom and the best sword in the shop, in Loguetown. Ippon-Matsu gave it to Zoro after he saw the skill and courage that Zoro showed in testing the curse of Sandai Kitetsu.
