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

Reason why I have asked is that there are sellers of Jaka who use material of dubious origin.
If it is from Radek then it is the original material. I know that for sure as we were together in the mine picking it. What puzzels me is the glittring in it. I will have to look through my collection of them. However I know that in the same meeting he was also giving out other hones e.g. Wallachian Sandstone hone.
I will take some photos of it. I haven't lapped it so it might be because of it, but I don't think so. As for the Wallachian sandstone, it's an excellent sandstone, at least the samples you gave us. I would love to get a big piece of both of them.
As for your 45x~20cm piece, is it suitable for honing, or a decorative piece?
To be honest with you that hone was originaly made for one of the directors for knife sharpening and then I have inherited it through his daughter.
I have flattened it but had never chance to put razor to it and recently even managed to damage it when I was moving house and the part of the collection which was there.
However if I wante to hone razors on jaka I have some higher quality raw material from the mine to make into usefull hones as well as few orifinal normal size Jakas.
@ Veselchack85: This looks a lot like the one I have, thanks a lot for the info.
