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 tachi by Sekishu Sadayuki, who worked from the end of the Nanbokucho period to the Oei era. The blade is signed and in ubu condition, which is rare for Sekishu swords. It features a bright hamon with a detailed notare-choji pattern and strong nie, with yubashiri and strong sunagashi.
