Special feature: Bishu Osadune Iesuke started around the Ouei era, the Muromachi period. There are many Ko-Wakizashi and Sunnobi Tanto but less Katana. This swordsmith school means swordsmiths who worked from the Nambokucho period to the
Ouei era in Osafune, except for the legitimate Osadune school swordsmiths. Famous swordsmiths among them are: Hidemitsu, Masamitsu, and Moromitsu(elder brother of Morimitsu). This blade has gorgeous Chojimidare with Ko-Gunomemidare. Nice Kozori work by Bizenden.
From Aoi Art: In Shinogiji, there is no Hi and some parts have rough texture. But elegant Chojimidare is beautiful. There are some small Kizu, but this blade is excellent because it has Saidanmei that are inlaid with silver and Jigane has no loose points. We truly recommend this to you.
