18 Nanbokucho time line

                           The circle indicate the time we are discussing in this section

During the Nanboku-Cho period, Samurai demanded large, elaborate and practical swords. Soshu Den style — elaborate, large, and impressive  —became the most popular style. Nanboku-Cho period was the height of the Soshu Den.  Many swordsmiths moved to Kamakura and forged Soshu Den style swords.  Other schools and provinces also made Soshu Den style swords in their own places.

Shape (Sugata 姿)—-Originally the length of the swords was 3, 4, 5, feet long, but shortened to approximately two and a half feet at a later time.  The sword shortened       a great length is called O-Suriage.  Nanboku-Cho sword has a shallow Kyo-zori shape (also called Torii-zori, refer 6. Heian period) — the highest curvature comes around the center of the body.  Widebody, high Shinogi, and narrow Shinogi-Ji (refer 4 Names of parts) and thin bodies are the characteristics of this time.  High Gyo-no-Mune or Shin-no-Mune, sometimes Maru-Mune (round back).
