Just picked this up.
I believe its a last ditch Japanese Katana. It is unmessed with and demonstrates genuine age and use.
Its locally made, the handle it beautifully weaved out of straw mimicking Ito braid, the blade is of inferior quality and bears nicks in the blade indicating use...the tsuba is plain iron.
The scabbard yet again is contempory and unmessed with retaining iron and straw mounts .
Over all the piece is very well put together...and not a tourist piece !!!!
Hope you like !!
All the best
