The Heian period is the time, the shape of the swords changed to the curved shape.  Until this time, swords were straight.

The study of swords begins from the Heian period.  The elegant and graceful taste of Fujiwara culture reflects on the swords that were made during the Heian period.  The preference of their lifestyle reflected vividly on the swords.  One of the active groups of swordsmiths in the Kyoto area was called Yamashiro school or Yamashiro DenDen means school.  Their style had a graceful shape.  During the Heian period, Yamashiro Den (school) represents the Heian period sword style.
