Unknown UK Stone

Got this the other day oily from the UK. Cleaned it and the box up found a name on the end of the box under the gunk. Took about an hour and a half to lap on sic and wet dry due to it being used for so many year had a big dip in the middle. Turned out to be really hard and smooth. A nice finisher and a skin friendly close shave. It is a little over 10" x 2 3/4" x 1" in a old pressure fit box.

Believe I have seen some stones that look very similar, forgot what they were called though. Maybe some Dalmore stone

Never had a Dalmore, but much finer than my understanding of a Dalmore. Also I believe Dalmore are more porous. All Dalmore I have seen where more of a grey blue. I have never heard of a green one. Does have a pattern sort of like one though.

Looks and sounds possibly like a Charney Forrest, greenish blue with brown and grey streaks. They are Novaculites similar to a hard Ark in performance, some will finish razors and are great knife stones, especially Carbon Steel knives.

They can be finished and burnished for a fine finisher. They were traditionally “Oil” stones but work just fine with water and a drop or two of Ballistol or Smiths Honing oil.

If it was caked in oil, it may take some soaking to get all the oil out. I soak in Simple Green or Awsome and water, it can take week or month to get it to release all the oil. Keep changing the water and degreaser until the water stops darkening.

Nice find, try finishing one side to 600 grit and burnishing the other.

Of course it is possible, but the color, composition and density all seem a bit different then the rest I have. Now I have another one that looks completely different, but everything else seems the same that I believe maybe an odd CF.

Looks like Welsh slate

That is one of my guesses too. Not sure how to prove it. The Glanrafon quarry had a Charley Forest stone which was a hard type of slate. This was difficult to lap and hard, but the resulting slurry had slate type properties to me. It seems almost like a hard schist type slate.

Nice. Mine is a green/blue almost aqua then bright green when wet.

Mine is purpleish...but there are several types of slate....

Slate, looks like schwedenstein but they are softer

I personally rule out a Schwedenstein...the patterns do look to different and there is not enough variation in color....

My guess is that it could be a „Genuine Blue Sharpening Stone“ from UK. They appear from time to time, often in smal wooden boxes. One example appeared as a bench Stone without box and label. The material looks blueish/gray with some nice looking patterns. Also there is a kind of a metallic look comparable to the french Special / La Lune Stones.

Here are some pics of the stones i own:

Pattern is definitely similar, but the color is very different. How hard is it and fine is It? The stone I have is super hard and dense and very fine. The color is more green aqua.
