    They surely looks the same and i think they are made by Imanishi company , so they are quality stones , but anyone try those on razors , as finishing stones ??????

    You will find cheaper equivalents if you look around. Nubatama is a stamp that Ken is using for common stones made by the likes of Imanishi.
    If you want a proven stone in the high grit ranges get a 8k Naniwa Junpaku (Snow White), the IF-0001 model, or 10k Super stone. From those you can jump on J-Nats/Thuringian with no problem.

    You can't shave with the 99.9% of the "finishing grit" synthetic stones. The shave is more harsh that anyone who hasn't tried one thinks is possible, and shaving with them is like shaving with an 1k stone. As already mentioned, there are a couple of exceptions.
    If on the other hand you want them for other edged instruments and you are sure that these steels are made that way that they can take the edge... no matter how much I rationalize it, I can't but think it's HAD.
    If you want a fine stone, the finest ones out there are the gokumyo 20k/0.5 micron. Nothing finer than that, no matter how many zeros they add before the k, and reportedly, the shave is not bad.

    I do recall reading about them a few years ago, and it was thought that for razors, they were not as good, softer than the Naniwa 12k super stone or the Shaptons and were pricy. This was before the GS20 became popular.

    I notice that Ken and Mark at CNTG are not stocking them.

    I do like the Nubatama stones in lower grits, though don’t see anyone in the US carrying the 15k.

    I have seen ken’s video and they do polish a knife edge but, no close up bevel pics. Still the 12k Super Stone is hard to beat.

    I have the Metalmaster 15K. I want to replace the 10 & 12K superstones in my progression, and I thought this might do it.

    It's not 15K.

    There might be 15K particles in there somewhere, but what you see on your bevel is the 8K scratches it leaves. Visible on the bevel from 2 feet away. Absolutely not what you want to see from a finisher. So it's basically an inconveniently-small (7x2") 8K.

    I've bought a number of natural stones from Metalmaster and been pleased with them. Unfortunately, I'm not wild about his venture into synthetics.

    My quest for a good bridge between 8 and 20K continues.
