During the Nanboku-Cho period, Samurais demanded large, elaborate, and impressive, yet practical sword.  The Soshu-Den style sword in Nanbochi-Cho time was just that.  This is the most popular style then.  The Nanboku-Cho period was the height of the Soshu Den.  Many swordsmiths moved from other provinces to Kamakura area and forged the Soshu-Den style swords.   Other schools and provinces outside Kamakura area also made the SoshuDen style swords in their own places.
