The subject sword is wide on base and is gracefully curved deeply even the tang is smoothly curved like a Tachi. Iori ridge is a bit low side , Shinogi is comparatively narrow to the Hiraji surface, those are the major characters during Bunka - Tenpo (1804-43) period.

The latter half of Edo preiod, city of Yonezawa in Dewa province (now south of Yamagata pref.), the most famed brother smiths "Kato Tsunatoshi" and "Tsunahide" who belonged to the great master "Suishinshi Masahide" school and also their pupil of "Akama Tsunanobu" had been very active.
The subject work of "YASUHIRO" shows the close resemblance to the ones of Kato brother (bizen-chool). It is quite rare to come across with his own the works. A possible reason would be that he had been playing a ghostmaker for his masters Tsunahide/Tsunatoshi long time.
