From Aoi Art: This work is slender and presents Uchizori’s Tanto
shape and Kitae generally has a Koitame hada texture and a rounded Kogunome Midare, which is a unique blade pattern that returns Bo-shi, Notare and Togari Gokoro. It is a work that has passed the era of 722 years. The year of Seian November 2010 engraved on the back is very valuable, and it can be said that Nagamitu with the year is extremely rare. Naturally, it is a work that was handed down to the daimyo family, and I would like to pay tribute to the fact that Tanto has been preserved so far for 722 years. Koshirae is a work of Issaku koshirae and dignity. We pray that it will be carefully preserved as a treasure in your home. Long signature and also Uramei is also a very valuable work.
