Special feature:Yonezawa shin Kato Tsunahide belongs to Yonezawa samurai and lived Edo Azabu branch office of Yonezawa cran, He was older brother of Cyounsai Tsunatoshi and called Tsunahide. In my opinion, it was the period when Suishinshi Masahide was making Toranba until around 13th year of Bunka, but his work with a deep nioguchi is easy to break. He began to produce works with straight blades and turbulence. Around the 6th year of Bunka, Omi Yonezawa and Tsunahide Kato, who were working hard to make Toranba, also worked together. It is thought that he was a disciple of suisinshi Masahide. Jitetsu is well-packed and Ogo-no-me, and Douranba has a wonderful blade pattern similar to Suishinshi Masahide. Cyounsai tsunatoshi also learned Doranba from his older brother tsunahide, but Tsunatoshi’s technique is inferior to that of his older brother Tsunahide, resulting in a blade that feels hard. Please purchase this wonderful work by Omi Yonezawa and Tsunahide Kato.

Tsuba: On the round iron tsuba, a water wheel, water stream, plants, and a bird are engrave.

From Aoi Art: Chounsai Tsunatoshi is well known as Cyoji midare hamon but his older brother Tsunahide is well known Doranba like Masahide or Sukehiro. Of course People have their preferences between Chuji ba hamon and Toranba, but I like this Tsunahide Toranba.
