Special Feature: Yasutsugu the 1st made swords also in Edo and was really popular. It is reasonable to think that it is made by the 1st, before he changed his Mei. In those days, he made a lot of Toshinbori(engraving on the blade), however the engravings of Hata and Hoko are extremely rare.
From Aoi Art: This work was made by Bushu Edo Echizen Yasutsugu, and has engravings on the blade. That blade is blackish and wonderfully made. We truly recommend this one for you.
Background: This work was made before Yasutsugu succeeded to Bushu Edo Echizen Yasutsugu, and in those days he used Mei of “Echizen Ju Higodaiujo Fujiwara Sitasaka”. Later he started to use “Oite Bushu Edo Echizen Yasutsugu(1st)”, and also the family crest of Aoi(althea).
