Aoi Art’s Comment:Gassan was a swordsmith from Dewa who was active from the Kamakura to Muromachi period.
During the Edo period, the tradition nearly died out, but a few individuals continued the craft in a limited way.
In the late Edo period, the Gassan tradition was revived through detailed study of the original Gassan-hada.
Gassan Sadakazu became especially renowned for this revival.
Even today, the techniques of the Gassan school are passed down.
