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 robust Yoroidoshi tanto made by Yasuchika, a Shinshinto smith from the Soshu school. Known for its thick kasane and uchizori, it is designed for piercing armor. The blade features impressive large itame hada with chikei and jinie, and a komidare hamon in ko-nie deki with various activities.
