Hamon : Niedeki suguha and noter with thick nioikuchui and sunagashi, kinsuji work.
Special feature : According to Honami Koson's sayagaki, the blade was judged as Enjyu school.
But NBTHK issued the paper as Kouda school.
The founder of the Kouda was Nyudo kunimitsu and many students like Kunifusa, Kunimune and Kunitsaugu.
Generally old Kouda make suguha hamon with sosyu den school.
This sword is suguha but sosyu den added with kinsuji work and a lot of Chikei.
The blade was judged as Enjyu by Honami Koson sensei but I think the blade was polshed and disappear Utsuri on the ji.
So NBTHK judged as Kouda school.
I think the polisher polished the blade more active jigane and hamon.
So the Utsuri disappear from the Jigane.
Anyway the blade was made around late Kamakura period fantastic jigane and hamon.
