One-of-a-kind Custom Japanese Military Dirk -- 1880's period. Custom mounts made during the time when Western military strategy advisors were in Japan to help them develop a modern army.
Note the frog stud--this is one of the features of the custom dirk mounts that date the koshirae to the 1880's.
Old nihonto blade by Mino Seki Kanemasu. Papered in Tampa in February.
