Naked Wakizashi blade
Blade length 48.0cm, thickness at the base 6.5mm, width 2.7cm
This is a naked wakizashi blade within pitiful condition. It is shortened from longer blade.
Hamon looks intact all through the blade. It looks like Mino tradition.

This blade is very suitable for amateur craftsmen for their practice. The hamon is very clear even in this poor condition. And it doesn't seem to have any fatal flaws. So it could turn to a nice blade by proper restoration work.
