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 wakizashi by Tadamitsu of Bizen Osafune, a representative smith of the late Muromachi period. The blade features a hamon of ko-midare choji with togari-ba交り, nioi-hon'i, and a midare-utsuri. The jigane is itame mixed with mokume, well-forged and refined. It comes with an NBTHK Hozon Token certificate.
