    Question Is it the (MST-) Thuri or a possibly a Silkstone?

    Hello all,

    can you please help my identifying this stone?
    It was laying around in my celar for a quite time but now I'd like to learn it more.

    Dimentions: 20.4cm x 5cm x 2.2cm
    There are some scratch marks on the sides:

    The stone feels harder than my YG-Thury, it does not produce autoslurry but slurries (color: medium-grey) easier than my Zulu Grey.
    The backside of the stone feels relativeley rougth to the fingers, perhabs similar to my belgian blue (BBW).
    But the working side is very smooth to the touch, think still does not reach the feel of the YG-Thuri.

    If I remember my first tests correctly on slurry the stone produces very fine edge with hazy bevel.

    The surface is black mottled:

    When I hold the working surface to the sunlight the surface looks shiny, hope its visible on the pics:

    Thanks a lot in advance

    Certainly favors one. I guess there would be more thuringians in Germany anyway!
    I'm sure one of the rock guys will chime in before long.

    Hi all,

    thanks for your hints.

    In a meanwhile i've done a bit more searching, seems like this is a british Cambrock Silkstone.

    I've found some posts from Hatzicho in other thread here and in a german-knife-forum.

    The surface pattern (homogenous grey when dry, cloudy when whet), the saw marks (fine parallel lines with a light curve in them, often seen as 2 sets of lines diagonal crossing each other like x-es), the size as well as the grit rating (almost rated as midrange to [pre]finisher) are matching to what I've found about the Silkstone.

    Best Regards

    It does somewhat resemble a silkstone. I have two that came in labeled boxes. Sawmarks look similar.

    Looks like a Silkstone indeed. Also the size is typical.

    Thanks a lot to all of you for your contribution!

    Ive played a little more with the stone in between.
    On slurry its working with a reasonable speed. I could achieve a solid HHT3-HHT4 of it, maybe with more carefull work it an finish on slurry.

    The scratch pattern leaved by slurry is a little bit rougher compared to my YG/B-Thuri.

    Looking forward to more experimenting!

    Regards
    Philipp

    Personally I prefer edges from these stones when used with oil. They are oil safe, it can be washed right off after finishing. You only need just enough to smear across the surface. 4-6 drops is more than enough for me.
