Shinto:Jyo-saku ranking:Oo wazamono cutting test ranking:Settsu.

(We divide 4 sections for each sword as Saijyo saku, Jyojyo saku Jyo saku and regular saku)
This sword belongs to Saijyo saku ranking.

The blade was polished by a high ranking polisher.

Blade length : 70.0 cm or 27.6 inches.

Shape : This sword is wide and long, a little shallow Sori, the Kissaki is longer.
Jigane : Koitame-hada is grained well with Jinie attached. Osaka Jigane.
Hamon : Yakidashi is straight, the rest is Choji-midare, Nioikuchi is deep and looks soft. There’re Sunagashi in the Hamon.

Special Feature : Higo kami Kuniyasu was the younger brother of Kawachi kami Kunisuke the 2nd generation.
Most of his swords have the fist-shaped Choji Hamon so-called Kobushi-Choji but this sword has moderate Choji midare.
He was rated as O-Wazamono ranking.

Koshirae :
Saya : Aokai Chirashi Saya.
Tsuba : Hexagon shaped iron Tsuba with the openwork carving.
Menuki : Shakudo Menuki, the acorn carving.
Fuchikashira : Shakudo Nanakoji Fuchikashira, the flower carving.

From Aoi Art : Higo kami Kuniyasu’s real name was Kobayashi Genzaemon, he was the young brother of Kawachi kami Kunisuke the 2nd generation so their style is very similar.
In my opinion, Kunisuke the 2nd’s Kobushi-Choji is intense while that of Kuniyasu is moderate.
As his brother Kunisuke the 2nd is very famous, Kuniyasu is kind of underrated, unfortunately. However, he left many nice swords also.
