T426.  Katchushi tsuba.  7.5 x 7.5 x .3 cm at the raised rim (the plate is .2 cm).  The nakago hitsu-ana is.85 x 2.3 cm.  Cloves are 2 of the sukashi; not sure what the other 2 are.  There are small tekkotsu on the rim and a few on the plate also.  The thin plate leads us to Ko-Katchushi (wouldn’t that be great).  I can’t guarantee it, shinsas do that job, but it is well made and in excellent condition.  $300.
