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 by Minamoto no Masakage, dated Ansei 6 (1859), features a robust, wide-bodied construction with a slightly extended fukura. The jitetsu shows fine ko-itame with masame mixed in, rich in ji-nie and chikei. The hamon is a varied gunome-midare with a pointed ko-maru boshi, reflecting the influence of his teachers Minamoto no Masao and Suishinshi Masatsugu.
