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 is a tanto made by Gassan Sadakazu, who was appointed an Imperial Household Artist in 1906. It features a hirazukuri, mitsumune form with a small stature. The blade has a suken carving on the omote and goma-bashi on the ura, with a vibrant hamon of suguha mixed with ko-gunome and ko-notare, showing active sunagashi. It comes with a koshirae featuring a paulownia maki-e saya and go-san kiri mon menuki, suggesting it was a special commission.
