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 katana is attributed to Katsumitsu of the Kashu school, active during the middle Muromachi period. Despite being greatly suriage, it retains a beautiful form with a wide difference in width between the moto-haba and saki-haba, and a sori that begins high on the blade. The blade features a strong itame-hada with masame, and a bright gunome-choji hamon with active ashi and yo. It comes with an NBTHK Hozon Token certificate and a robust ishime-nuri han-tachi koshirae.
