A beautifully Uda-den koto katana that has high quality workmanship and a beautiful gunome/midare hamon with utsuri.  Many hataraki/ activity can be found with  Sunagashi, Kinsuji, chikei, Ji-nie and utsuri can be seen also. Ida school swords come from the Yamato tradition and this can be seen and appreciated within this blade made in the old Yamato tradition. The condition of this koto piece is wonderful as can be seen in the pictures. A very robust Hamachi and Munemachi can be found.  It is in a good polish. The pictures not do justice to this sword.  The hamon is very nicely done with a thick nioi-guchi that flares up here and there..  It has many hataraki and ko-nie appear.  The hada is very well forged with a very slick looking color of swirling  itame with mokume.  The boshi is ko-maru with kaen like finish and longish. This koto katana has an elegant shape and is very well balanced. The curvature is very noticible and is text book UDA.  A very interesting thing to note on this blade is that the mune is maru and so is the mune on the habaki. This is not a common straight on swords in general. The blade is papered by the NTHK attesting to the swords quality, age and school.  The blade is in shirasaya. Overall this is a fine Japanese Koto katana. the blade also comes with a beautiful rain pattern solid silver habaki.
