The characteristics of Yamashiro Den swords

Sugata(shape)—– In general, the blade is narrow, especially near the Yokote line.  The bottom of the blade has fundari (A-line shape).  Kasane is thick.  The curvature type is usually Kyo-zori (the deepest curvature comes at about the middle).  It has a small Kissaki with Fukura.   Shinogi is thick with Gyo-no-mune or Shin-no-mune.  Please see the three illustrations below for Sugata.
