Special feature: Bicchu Aoe was founded by Yasutsugu in the Heian period. They flourished a lot and many swordsmiths left unique masterpieces. We call items before the Kamakura period as “Ko-Aoe(old Aoe)” and the items between the late Kamakura
period and the Nambokucho period as merely “Aoe”. Inscription(if there is,) is engraved as Katanamei mostly, seldom engraved as Tachimei. Most works get Sumihada and Jigane tend to be Chirimen surface. Many swords have reversed Chojimidare hamon or Sakaashi. Many sword fans love Aoe school.
From Aoi Art: Aoe school is loved by lots of people around the world, and their works are very unique. Especially, their Jigane is Chirimen(silk crepe pattern). Hamon is mostly reversed Choji. This work has dense Mokumehada and beautiful Suguhadeki hamon with Koashi. Sori is deep and Kissaki is long. It is made really well in good condition. We truly recommend this to you.
