This is a large wakazashi (almost katana size) and is a very sound and healthy blade and appears to be in an older koto style.  The blade is wide and has a beautiful curvature that reminds one of the old mino school.  The quality of the sword is also good.  The hamon is bright and has very good activity.  The hada is milky looking and is forged well with much ji-nie and shirake appears.  The hamon is frosted with nie and the hada is a tighly well forged mokume with itame. There is profuse ara-nie and ji-nie. This sword is signed by Akasaka kanesada. There were many Kane Sada smiths working at this time but this sword is of a distinct branch. The hamon is notare midare in sugu-ha with much activity and plenty of nie with nioi. The hada is a mokume mix.

Though in need of a fresh polish this blade has good work. it comes with original koshirae though the lacquer is missing in spots. The fuchi kashira are iron with a gilded design. The tsuba is made of shakudo. The ito and sageo are both in black with a well made habaki.

About Akasaka and this smith:

Akasaka-jû Kanesada
赤坂住兼定

Akasaka was a production site in Mino province. The famous Kanemoto lineage worked there as did a branch of the No-Sada’s. The group around No-Sada worked in Seki but the banch in question split off and moved to Akasaka. That was in the late 1500s, i.e. Tensho (1573-1592).
