From Aoi Art : Ho-ki Kami Masayuki and Motohira are both pair of bright
jewels and the most well known sword makers in Satsuma.
The style of the jigane and Hamon both tried to make Shizu or Sa mainly
deep nioikuchi active wavy temper line.
Masayuki and Motohira’s nakago is slightly different other sword makers.
The bottom of the line of nakago is slightly different from center
of the nakago. Koshire is very good quality without scratches and Kizu.
all matching tiger and bamboo. We strongly recommend this sword with Koshirae.
Motohira and Masayuki : The shindig line must be slightly different
from the center Nakagojiri. If the shindig line reached to the center of Nakagojiri,
you should doubt the blade might be Gimei(fake)
