Aoi Art’s Comment: This piece is likely a reproduction of works by Kagemitsu from the Kamakura period.
At a glance, the length, curvature, and bo-hi resemble works from that time.
However, it has little utsuri and the hamon has a slightly rigid impression.
It is an excellent work by the master swordsmith Ishido Fujiwara Korekazu.
*There is a rusty area on Mune of Kissaki. If you wish to polish it, we will need a few months for it.
