This katana by Kusano Yoshiaki, a student of Gassan Sadakatsu, features a wide body with deep bo-hi for reduced weight and improved handling. The jigane is a tight masame-hada with fine chikei and thick ji-nie, while the hamon is a bright chu-suguha with ko-nie, yubashiri, kinsuji, and sunagashi. The blade comes with a han-dachi koshirae featuring a unique lacquered saya and a hilt with gold dragon menuki, themed around water deities.
