Sorry for my bad english. I'm from Russia. This Czech black slate, working in the area of 6000-8000 grit. Obtained in the Czech Republic so far, but the quality has deteriorated stones, there are inclusions of pyrite. a couple of years ago, the quality was higher.

From the side it looks liek a WOA and Tam O shanter to me, (I had a Tam with similar patterns to the lighter tone you have side on view.) I have a couple of Czech hones but they dont look like that.

The WOA and TOS stones did not come from the same quarry like coticule/BBW. This stone is a natural combo and doesn't look like a WOA either, so we can safely assume it's not.
It could be the JaKa stone (I have a strip from one, the surface kind of looks like this one but it has "sparkly" particles on close inspection although uniform), but there are hundreds/thousands of slate/shale deposits in Europe. From these even if the primary purpose of stone extraction is decorative slate, many of them contain material that can be used as a hone, and possibly a really good one. We know the 20 or so most famous, but there are a real lot more out there, either waiting, being extracted, or being already emptied with glorious hones decorating floors and roofs. Like the mine of the JaKa stone.

Czech stones also feature high hardness, get to their suspension, using a small piece of the same stone, it's very difficult.
With all respect, Andrey.
