#28) Koyama Munetsugu with  NBTHK Tokubetsu Hozon paper.  In shirasaya. This blade measures 23 9/16 inches or one shaku 9 sun 8bu or 60cm. I am calling this a waki/katana. In the Japanese measurement we call 2 shaku a daito and 60cm a daito but in Western style we call a blade of 24 inches a daito.  No matter what this large construction would have been mounted as a daito.  Very fine itame lamination work. Temper is choji. excellent condition.
