    If you own naguras you could use for that purpose, yes the C12k would be a good option.

    30k for lapping stones? Wow! I don“t think this would have any effect at all.
    I have the Shapton 'fine' powder, which is said to be ~4k

    The 0.5µm Alumina was a gift. Unfortunately I don“t know where he got it from.
    I guess it was this site (german only)
    Siliciumcarbid Schleifpulver - Schleifmittel SIC Siliciumkarbid - Mineraliengrosshandel Hausen GmbH - Onlineshop für Edelsteine Rosenquarz Bergkristalle Trommelsteine Siliciumcarbid Amethyst kaufen

    yeah, I“ve seen that one before. This is kinda how I used the 0.5µm Alumina on the C12k

    I wouldn“t necessarily recommand that for straights (never tried it) but for kitchenware and tools,
    it works. But I wouldn“t do that on my Maruka, because mine is as fine as heck, even without 30k SiC

    I used the exact same method on my Ohira (~8-9.000) with 0.5µm Al2O3 and two kitchen knives.
    The results where comparable to the C12k with Al2O3. If you use a heavy slurry like in the video,
    you will notice a strong, really really strong polishing power. I have to buy a whole package of the 0.5µm Al2O3 one of these days.
    At the moment I only have a small sample and am a little hesitant to use it

    Thanks for the info.

    Now I must see that Maruka stone of yours!! I was thinking of buying
    such a stone, but 1500-2500 USD(200/75/30mm size) is not something I can pay.

    I would guess for razors you would need a very little slurry, unless you
    would skip the intermediate stone between the sharpening stone and
    the polishing stone. Sic grit is very hard and would quickly achieve this.
    Aluox probably would do this as well.

    Here you can see my Maruka/Maruichi.

    Did you have a look at the shop of Maksim?
    He lives in Europe and is a very friendly guy.
    He has some great japanese naturals.

    Just yesterday I bought a Shoubudani from him that I am looking forward to very much.
    His prices are highly acceptable and he can help you with your search.
    I suggest you send him a message,
    because you should not pay more than 400€ for the best japanese natural I can think of
    You can get equally fine stones for much less if you are willing to accept inhomogeneties in colour,
    or small chips on the back and razor-stone size etc.

    Here
    you can see him use the stone that is now mine

    I wonder if all these “guanxi” stones sold by various sellers are the same

    If you can afford to buy a decent Japanese natural then a Guangxi might just be a waste of time for you. Between a €15 Guangxi and a €400 Jnat there are several good alternatives.

    Nice stone, looks very beautiful.

    Yes, I know Maxim, I asked him for a flawless stone , but he could not help
    me for the price I was thinking. Don't blame him. I am wondering how much
    his ozuko asagi cost.

    I had seen your stone before. Looks very nice, good size. Hope you will
    enjoy it!!

    What do you consider flawless? In J-Nat terms that would mean 100% homogeneity and perfect size. This is hard to come by.
    The Stone shown in the video (soon o be mine) is far from flawless. My Nakayama is, too.
    But all are carefully selected, without inclusions or cracks that can affect the performance in any way.

    The C12k usually comes without cracks, but has lines and patterns.
    But, like with J-Nats, these are considered likeable.

    If you can afford to, I would recommend one of Maxims razor sized Ohzukus (if you want a non-beginners Stone), or another stone.
    You will probably not get a flawless one, but one that will perform flawlessly

    What is the difference in a beginner and a non-beginner Jnat? What is the lowest price you can get a nice one for finishing? I was thinkng about getting a smaller one to start with. It doesn't bother me if it is butt ugly, or the underside has cracks, chips etc, if the honing surface is good, and the edge off of it is too My finest stone is a nani 12k and a vintage thuri, so I would love a Jnat in this range, or maybe a bit above. I don't see any reason to get a Jnat if it is an inferior finisher to my existing stones.
