The Middle Kamakura period was the golden age of the sword making.

I displayed the above four photos several times on different pages of this website. Those were Mitsutada swords, once my father’s sword. Those photos were taken by him and the writing on the white paper is also by him. He was very proud he collected four Mitsutada and he monogrammed the name Mitsutada inside his suit jacket. It is said that Oda Nobunaga (織田信長) with his wealth and political power, he collected 28 Mitsutada. I realize those photos are not wonderful pictures. To avoid causing any infringement of the copyright and intellectual property rights, I only use father’s photos (not so wonderful though), Sano Museum Catalog photos ( permission granted), and some public domain photos from Wikipedia. Please bear with me that I don’t have good photos.
Bizen Osafune Nagamitsu (備前長船長光)
Nagamitsu is Mitsutada’s son.
Sugata —– Shape is similar to the one of the early Kamakura period style. That is with Funbari and narrow at the top. This is called Nagamitsu Sugata.
Hamon —– Wide tempered line. Nioi base. O-Choji Midare (large clove shape) mixed with Kawazuko Choji (see below). Many Ashi appears. Also, he does Suguha-Choji (straight with choji mixed). Works of Inazuma and Kinsuji shows.
Kawazuko Choji on the above sword is very clear, and almost textbook like example. But often, they are not as clear as this one.
Boshi —– Yakizume or turn back a little.
Ji-hada —– Fine wood grain. Well known for Utsuri (shadow). Choji Utsuri (Shadow of Choji) or Botan Utsuri ( resembles flower peony). Choji Utsuri shows in the above picture.
Below is the poster of the Museum of Tetsu in Sakaki in Nagano prefecture in the year of 2003. The photo of the poster is Nagamitsu’s sword and Koshirae (scabbard). It was a family sword then. Toyotomi Hideyoshi (豊臣秀吉) of the Sengoku period awarded this sword to Takenaka Hannbei (竹中半兵衛: Hideyoshi’s strategist).
