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 is a katana made by Yokoyama Sukemitsu, who was born in Edo Aoyama and studied under the Yokoyama school in Bizen Osafune. He was recognized by the lord of the Mito domain, Nariaki, and became a retainer. This particular blade features a large kissaki and a hamon with gunome mixed with ko-choji, reflecting the style of Nagayoshi from the Nanbokucho period.
