Edo was the sword’s age of connoisseurship: the Hon’ami appraisers, the shogunal register of famous blades of 1719, and a thriving literature turned the sword into an object of study even as it ceased to be drawn in war.
This tanto is signed Yasuoki, the early name of Hashiguchi Kansuke, who later became the 61st generation Naminohira Hiranori. Made in the late Edo period (around Tenpo era), it exhibits a robust form with a wide body and thick kasane, characteristic of the Yamato tradition. The hamon features thick nie and deep nioi-guchi with gunome interspersed in suguha, while the jigane shows ko-itame with some hada-tachi and masame near the mune.

A Hozon-certified blade judged to show notably superior workmanship and a better state of preservation. The bar is higher: re-tempered blades and most unsigned Muromachi/Edo works are excluded.
