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 katana is signed by Izu no Kami Masafusa, a smith from Satsuma province active in the early Edo period (Shoho 2, 1645). It features a robust form with a wide mihaba and thick kasane, showcasing a well-forged jitetsu with rich nie and nioi. The hamon is a tranquil suguha with small gunome and ko-ashi, exhibiting an old-style charm reminiscent of Horikawa Kunihiro.
