Vintage IWASAKI Tamahagane Kamisori 45mm Japanese Razor
It looks it had been used and sharpen for a while by former owner.
The normal width of the blade is 20mm in 45mm Iwasaki Kamisori, and this kamisori has approximately 18.5mm width from the shoulder to the edge.
It has rough grit finish on the bevel on the concave portion, so the former owner tried to dig some more concave.
It has “K” stamp on the handle which has never seen it before.
I have seen serial numbers on the handles in older models, but I have never seen it.
Mr. Iwasaki and Mr. Mizuochi told me some examples of meaning of abbreviations, but they could not remember all of them without looked into the documentation, so I guess they put on lots of abbreviations.
It should be one of them.
Overall, it is still in excellent condition to me.
