Ipponmatsu

Ippon-Mastu was the owner of the weapons shop in Logue Town Zoro visited. He was the previous owner of two of Zoro's swords, Sandai Kitetsu and Yubashiri.

After being impressed by Zoro's willingness to test his luck against Sandai Kitetsu and its curse he gave him Yubashiri for free. Yubashiri was his familys heirloom, a sword passed down through his family from one swordsman to the next until it reached him. His willingness to part with the sword, he told his wife, was that he was simply passing on to Zoro his dream.
