Inoue Izumi kami Kunisada
Special feature : This blade was made by Inoue-Shinkai.(Inoue Izumi no kami Kunisada.) As his father was so old, Shinkai forgeed on his behalf.
Examining the workmanship, we completely convinced with this opinion.
Inoue Shinkai was born as the Second son of Kunisada the First in
1630. Shinkai used the swordsmith name Kunisada on his early works.
