Special feature:It is an accepted opinion that Tametsugu was
a son of Go (No) Yoshihiro and learned under Norishige though
there is still room for more research about the difference
of chrono-range among them. Both Yoshihiro
and Norishige were counted among ten brilliant pupils of Masamune.
Norishige created a peculiar texture of jitetsu
compounded soft and hard iron commonly called matsukawa-hada
or Norishige-hada in Japanese.
From Aoi Bijyutsu: Tametsugu’s works in Echizen province
dated in 1357 and 1369 are still remain on the record as oshigata pictures.
An extant inscribed Noshu Ju Fujiwara Tametsugu in 1374 shows
he moved to Mino province from 1369 to 1374.
Judging from the texture of jitetsu, this katana should be attributed
to Hokkoku-mono, forged in the northern province of Japan.
Deep-nioikuchi, thick nie, many sunagashi and kiusuji
form an attractive temperline of Tametsugu.
Both jitetsu and hamon create a healthy impression.
At a glance, the blade looks Norishige hamon which is very very
active wonderful texture and hamon.
