Hamon : From the Hamachi, nioideki suguha and then Choji midair
and Juka choji midair mixed.
In Ha, ash which is very soft feeling and round shape Boshi.
Special feature : At the NBTHK, judged as Yokoyama Suketada but I think If the suketada, The Hamon is more simple.
So I think the blade looks like Yokoyama Sukekane first generation because the Hamon is very active without faults Juka Choji midair which is typical nice Sukekane.
Even though the blade is unsigned Ubu naaakago,
the blade is very nice Jigane and Hamon.
We recommend this sword for you.
