The real name of the Kato Tsunahide is called Kato Suketaro.
He was born at Dewa and worked for Yonezawa family.
He was older brother of Kato Kunihide. He and his younger brother Chyounsai Tsunatoshi moved to Edo and studied under the Suishinshi masahide.At that period, Doranba hamon is very popular and studied this technique his master Masahide. He made Doranba hamon with his younger brother Tsunatoshi. We have some chances to see their Doranba hamon. This sword is high quality doranba hamon with Tama(circles). They adore Sukehiro’s doranba oogunome hamon.
His master Masahide stopped to make Doranba hamon because he found the thick nioikuchi doranba is
easy to brake devided 2 pieces during battling. So his mind became reactionary emotion and made swords
which is not charm and somberness hamon but cut well sword.
The doranba which were made by Tsunatoshi and Tsunahide are not thick nioikuchi sword.
So they changed the Doranba not thick nioikuchi hamon like their master.
At modern times, the sword collectors like thick nioikuchi Doranba hamon like Masahide is wryness.
The sword is the top ranking Tsunahide sword.
We recommend this sword this fantastic active hamon.
