Tashiro Genichi kanenobu was working during the  Syoho era(1624) from Mino province.
Kanenobu adored Kanemoto sanbon sugi style and his work and this is reflected in his own work style.
In the Edo period, Kanenobu, Darani and Katsukuni are well known sword makers for making sanbonsugi hamon.
This sword is beautifully made and appears very sharp.  The sword has an abundance of hataraki/activity in the hamon.The itame hada is forged well and its in an original older polish.  In a fresh polish it would be exceptional, but the work can still be enjoyed in the older polish. If interested in having use polishing the sword for you the total price would 2000 for polish. Saya lacquering would be a little more.  In the end the work would be worth the effort and would increase the value of this fine sword.  The blade comes with its original mounts.  The habaki is not pictured but is solid copper in good shape.  The handle is very interesting in that its lacquered leather with honest samurai fittings.  The mounts are not flashy but of good taste.  Kanenobu is a Jo-Saku level smith.  The papers attest to the smith and quality of this blade.
