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 antique katana is signed by Hisakatsu (久勝), a smith of the Akasaka Senjuin School in Mino Province, and dated to 1513 (late Muromachi period). The blade exhibits characteristics of both Mino craftsmanship and the Yamato tradition. It comes with a Tachi-style koshirae decorated with chrysanthemum and paulownia crests, and is accompanied by an NBTHK Tokubetsu Hozon Certificate.
