Work and style

Short, narrow and elegant blades, with a small, gentle midare: this is how the NBTHK describes the work of Norimitsu, and the katana of 1459 is its best example.

Kantei keys

Sugata
Many short and narrow blades, with a difference in width between the base and the point, a somewhat small point and a small, elegant shape, according to the NBTHK. For Sesko, the shape of the mid-Muromachi period: shorter nagasa, more taper towards the point, thicker kasane and more sakizori, in the passage from tachi to katana. HD
Jigane
Well-tightened ko-itame with fine ji-nie, in the katana of 1459 HD
Hamon
A small, narrow midare, with the peaks somewhat apart and some angular stretches, ko-ashi and yō, gentle in feel, according to the NBTHK. Sesko cites him among the Sue-Bizen swordsmiths with elements that open towards the base (腰の開いた, koshi no hiraita) and among those who temper nioi suguha. HD
Bōshi
Of a not very wide temper, according to the NBTHK; on the katana of 1459, midare-komi with a ko-maru turn-back. HD
Nakago and mei
On the katana of 1459, an unshortened tang (ubu), kurijiri tip, katte-sagari file marks and two holes, with a long inscription on both sides HD

The katana of 1459, piece by piece

  • Shinogi-zukuri, iori-mune, a slight sakizori and a medium point (chū-kissaki); 68.1 cm long according to ColBase, with 1.9 or 2.0 cm of curvature. The Japanese Wikipedia gives it 68.2 cm, and Sesko 71.6 cm.
  • A gunome-midare hamon with ko-notare, with a tight nioiguchi, with many ko-ashi and yō.
  • A bōhi with soe-hi on both sides and, below, an engraved bonji and goma-bashi.
  • The Japanese Wikipedia describes it as somewhat slender but of very good steel and very good temper, and as one of the most representative works of Sue-Bizen. ColBase highlights its clear steel and its showy hamon.

The change of the Eikyō era

According to Sesko, from the Eikyō era (1429–1441) the elements of the Ōei-Bizen gunome-midare become smaller and narrower, and the valleys drop towards the edge; the hamon tends to carry yō. That Eikyō-Bizen is the intermediate step towards Sue-Bizen, and Norimitsu one of its names.
