After the Ōnin War broke the Ashikaga order, a century of Sengoku warfare armed nearly every province in Japan. The era rewards a discriminating eye: routine work exists in quantity, and beside it stand custom blades of the first rank.
This is a tanto by Yoshimitsu from Tosa province, active during the late Muromachi period (Daiei era, 1521-1528). Yoshimitsu is considered the oldest swordsmith in Tosa and is associated with the Yamato Tegai school. The blade features a thick kasane, narrow mihaba, and uchizori, with masame grain mixed in the jigane. It comes with an aikuchi koshirae with a black lacquered saya and is accompanied by an NBTHK Hozon certificate.
