Special feature : Kurihara Nobuhide is a top ranking swordsmith very well known as a student of Yamaura Kiyomaro.
Nobuhide has born at Echigo province, Niigata prefecture now. He became craftsman of mirror at first and then changed his job to the swordsmith.
He was also skillful at engraving Horimono.
On Meiji 5th(1873), he forged special Katana for Emperor Meiji.
Generally student must follow his master but the swords forged by Nobuhide were made with his own style on both Hamon and Jigane.
Homon or Kiyomaro are gentle from Hamachi area but Homon of Nobuhide goes opposit way. He made very active Hamon from the Hamachi area.
I think the Nobuhide is one of the top ranking sword maker in late Edo period.
This sword is having very active Soshu style Hamon with attractive Jigane.
Wes strongly recommend this sword.
He lived in his hometown for the rest of his days, but one day he suddenly went to his daughter’s house at Tokyo and passed away at Meiji 13th (1880).
