Same here, the more I looked at it, the less sure I was. Whatever happened to Howard anyway, the guy sure knew his stones.

My first thoughts were that it's some sort of slate. No one else thinking along those lines?
Here are pictures of the one I had. The bottom was pretty rough, slate like I think. It was originally used with oil.
It feels smooth except for the middle, it may be coarser than a Coticule.
Its definitely nowhere near a Charnley Neil...do you think it may be a Cutler's Green?
There is so little info out there on the Cutlers that I just don't have a clue. I don't think it is a slate as the slurry produced is white with a slightest hint of the shade of green of the hone. I think slates have dark slurry as far as I know...
I've been playing with the hone a fair bit and its not the most useful of hones. Then again life would be dull if all hones were highly efficient.
Piet - I think that's the same stone! Yours is extremely thin like mine too, literally a few mm. Did you use yours at all?
My stone wasn't that thin, more than 2cm I think. I did use it several times expecting it to be a fine finisher like a Charnley which it wasn't. It was sold to me as one. I couldn't tell if the stone had a uniform grit or if the middle was coarser which was a bit frustrating.
Reading about your experience I now think the whole stone has the same grit but just feels a bit different in the middle.
Recently I bought another one just like it. Grey with a hint of green, definately softer than a CF or Llyn Idwal and not as smooth. The straight transitions seem to be characteristic for this stone. It's 24 x 5 x 3 cm in size.
