    I learned that coticules are non-porous. Water can sit on it the whole day and no seep through. Hindostan stones are porous.

    You cannot make sweeping statements based on just a few examples, Jerry.

    While low grade, low grit hindostans may exhibit porosity, the higher grade, high grit ones are not porous. I have dealt with quite a lot of them and can tell you for fact that any hindostan around the 9k, 10k and higher grit equivalent are glassy smooth and non porous.

    While the great amount of coticules are non porous, there are examples of porous and semi porous ones.

    Natural hones excel at not conforming to preconceived limits.

    Fair enough Neil. Thanks for the knowledge. I wish I can one day find a Hindostan stone that is of such fine grade that it is non-porous to use on my straights. At least now I know they exist and I'll have a blast when I find one.

    Just today I received three PHIGs from Woodcraft and I thought they would be super hard as I've read from the forums. However they were real easy to lap with my Hindostan stone. Almost as easy as lapping the slate backing of my coticule and much easier to lap than my translucent and surgical arkansas stones.

    Regards,
    Jerry

    So what's the good news? Did you find out what type of stone it is? New pics etc.?
