Thread: Haven't a clue?

Bought this hone the other day on a whim. I have tried it and found it produces a very good edge.
Can anyone identify the type?

Would you mind posting some further more shots, probably from both sides/endings if there are sawmarks and a detailled shot from the surface...

I only have a phone camera so not sure I can do better but here are shots of the ends

Previous owner made a week attempt at splitting it. It is 2.5"wide, 7" long and a full 1.5" thick. It is quite a hard stone but can be scratched with hard steel. Sedimentary type striations can be seen under magnification. What is the back of the stone shows processing saw marks and the ends look hand tool cut and finished with a scutch comb chisel/hammer.

Just looking at the colour it could be a Hindostan, if this one has sedimentry layers this would be another identifier... At this stage its only a guess

Cheers for the suggestion. I have used it with oil for my work edge tools and I am very pleased with the edges produced but with water for my razor it produced a great edge and on a par with my yellow/green Escher. It would be nice to put a name to it.

Thats an example of my Hindostan as you can see the sedimentry layers....

this might help to compare to the stone you want to be identified...

It's Def not the same as your Hindustan. H
My stone has a plastic look about it and no granular texture. Almost a hard cheese look. The surface that's been used has a polish to it now from honing. What I called striations are so indistinct to the naked eye and look more like a very feint discolouration.
Nice hone you have the tho!

Color made me think Hindustan as well, but my limited experience with them does not allow me to consider them to be as fine as described. Have you tried lapping it? I'm wondering if it is a double thick coticule. The few that were not BBW or slate backed tended to be thicker because they were relatively fragile. Coticules make a milky white slurry, but then I would expect any hone that color to make a white slurry.

@utopian:
Another idea i had on my first thinking but did not post....so this might be a good guess
