MASAMOTO So Honten Usuba 240mm blade W/ Octagonal shaped Magnolia & Water Buffalo Ferrule Handle and Magnolia Saya
This knife looks it has never been used with Saya, the original box, and the paperwork
I think the box is older one, so it might be made decades ago.
Overall, it is mint in box.
I am not sure what kind of the steel with the blade.
I guess it is white or blue steel kasumi blade.
