The Haitōrei edict of 1876 ended sword wearing and nearly ended the craft itself. Military demand and imperial patronage kept a remnant alive, and in 1906 Gassan Sadakazu and Miyamoto Kanenori were named Artists to the Imperial Household.
This Shinto katana is a masterpiece by Gassan Sadakazu, an Imperial Household Artist, featuring intricate carvings of a dragon and sanko-ken by the smith himself. Dated August 1910, it showcases his renowned 'ayasugi-hada' grain and a hamon based on ko-gunome with pointed elements. The blade is accompanied by an NBTHK Tokubetsu Hozon Token certificate, highlighting its exceptional quality and historical significance.
