Masayuki. Or his sword and Okachiyama Nagatada was changed to old famous sword
by removing the signature and cut shortened the blade.
This sword is mentioned exactly same sword at Shinshinto Taikan.Page524 rhwe book
says that the blade is the blade is healthy and good work and looks Masayuki. also
another Masanao passed Jyuyo token.
The reason why he was studying Masayuki and Motohira is that the Nakago line reached
a little aside of the bottom line. This mark is a major feature of Motohira and Masayuki,
and was made to prevent counterfeiting.
If this hidden mark is still valid and there is no such mark at first glance, it is judged as a
