I just bought a japanese whetstone and would like some extra knowledge . It is dated 1929 on the bottom of the stand it is a finishing hone for razors and has a drawer to place a razor inside the stand . The person has just sold a Narutaki exactly the same but it had a sticker but he said this one is nearly identical with the exact same stand. I have read that the japanese natural whetstones from this mine are the best in the world. Any information would be appreciated. I dont have the stone yet and will post a picture soon as I get it.
