    Never tried it though.
    It is a fine hone for both knives and also for resetting
    the bevel on a str8.

    It is fast -- the slurry quickly turns black from
    the steel it cuts. It is not so soft that it
    dishes out from under you.

    I used it on a razor from New York
    and it cuts "hard American" steel well.
    I used it on a German kitchen knife
    and it was happy to hone and polish.
    I used it on a couple of Shun classic
    kitchen knives and the very hard VG-10
    gave it no problem.

    It is a good 2K hone.
    I plan to enjoy it for resetting bevels
    on shavers when laps on a 10K
    or 12K no longer does the job
    (i.e. no need to go up to a 1K).

    I also plan to use it after my Norton 1K
    hone when setting a new bevel. It very
    quickly removes the "roughness" that
    the 1K seems to deliver.

    With some limited tinkering it might deliver
    a better polished edge than half my barber hones.

    Highly recommended for those with HAD.

    At this point the Aotoshi is not a line it is a point.
    It has only one example.

    It is softer than both the Superstones and Choseras. The biggest
    thing I noticed is that it makes a slurry just by using it. It has a
    lot of grit and you can hear it cut sort of like the old soft shoe dance
    with sand on the stage. It apparently polishes more than the Norton 4K
    side of a 4/3k combo perhaps because there is so much abrasive in
    the hone.

    I have tried my 10K Chosera dry and it seems to like this mode
    on occasion. I tried the green brick dry and it seems to clog
    with swarf quickly perhaps because it cuts steel so fast.

    If you love sharp kitchen knives get one.

    If you have a box of shavers (already well honed)
    you will not need a coarser hone in the kit. I think
    it will let me focus on polishers and finishers.

    It is perhaps the most satisfactory HAD induced purchase
    I have made.

    Does it need soaking?

    I think the stone has natural abrasives which break down and thus provide much better polish than the stated grit of the stone.

    Yes but not a lot.
    Soak it for five to ten min and if it wants more give
    it a splash more of water from a pan or the sink.
    As the slurry begins to dry it begins to act like 'mud'
    with a small splash of water it is cutting again.

    It uses white fused alumina, the same as the superstones and chosera. The binder is different, though.

    thanks for the clarification, I was under the impression it was similar to the Imanishi Aoto, but never really checked into it.

    How does it compare to a Japanese natural Aoto?

    Similar how? The only description I can find of the Imanishi stone says "It uses a mixture of #1000 and #3000 artificial abrasives to reach an average of #2000" which sounds, to me, like a bad idea.

    The Aoto has natural abrasives too, this is a very popular stone for knife sharpening because the composition. Imanishi uses natural stone material in their Takenoko 6k or the identical Arashyama 8k stone too.

    EDIT:
    I checked with some people that used to sell the stone, it is not confirmed that it has natural abrasives in it, it looks like it is misinformation floating on the forums. One vendor is listing it as having natural components though.
