Shape of Sword : Early Muromachi Period
What influenced the change in the shape of sword made in the early Muromachi period? (1394-1466)
The shape of the early Muromachi period swords somewhat resembles that of the early Kamakura period. The battle of the Kakitsu uprising, where Samurai had to fight indoors, changed the battle method and had a large influence on the shape of the swords of the time. In order to wield a sword in the small space swords became shorter, so the WAKIZASHI (脇差) grew in demand accordingly.
The swords of this period had their deepest SORI(反り) located above the center of the blade, so the blade could be unsheathed both quickly and easily.
