T469.  Yamagane tsuba with a shakudo fukurin.  7 x 7.5 x .4 cm on the fukurin (.3 cm on the plate).  The nakago hitsu-ana is .8 x 2.7 cm.  This one looks like it has been around a while.  There is the slightest hint of amida yasuri (see my 4th picture); they give a faint shimmer to the plate in sunlight.  The small ryo hitsu is unusual as well.  $150.
