@Bugyotsuji I can not understand the link, where you are coming from, there is a kamon, I apologize in advance.
@Steves87, yes it is strange indeed, on the other side nothing is gone. When I received it it was very dirty and it looks like there was old oil on it. there it is oiled, dry in a piece of furniture and next week cleaning with a soft cloth and re-oiled again. Is this the right technique? There are so many.
I will show it to someone to see, but the weight is good I think and there are similarities with the link of another Nami tsuba @Spartancrest, maybe that of a student or less expensive order.
@ROKUJURO It would be a shame if my second tsuba in a row is not yet a true quote. Go a little depressed there.
