Who has a similar uk green hone?

Got this the other day. Have been fighting it with 120 sic. It seems to be slate. The slurry has a hint of green in it. There are scattered black dots. A few surface ripples, it's dense and while it laps material away readily, it takes a lot of effort even with sic to get where you're going. It was used with oil but the oil did not seem to penetrate really even though the box was so saturated it soaked oil into the packaging. It was littered with razor breadknifes as well as channels from fine points being honed. Color is a rich drab green for one half transitionng to a green on the other end with hints of yellow peeking through.

I will take some new pics when I have the primary surface true and polished. No point in ul pics of the surface bitten matte by sic

One of my friends has one. Also from the UK. His has skin on the backside looks like a jNat. He thinks it's a lIyn Idwal.

It's a pretty sweet stone but nothing super special.

Looks like a Llyn Idwal, Grecian, and was probably used to sharpen gravers. 60 grit Silicone Carbide from Got Grit.com and a cookie sheet will get you flat in about 20 minutes.

There are many flattening threads in the Hones forum, search flattening Arks. Nice looking stone, some are finishers.

Here is a good thread. Hone ID Green stone

It's not novaculite fwiw

I don't think the one I tried is novaculite either. I've found a picture of the one I mentioned before. It's the big one in the middle.

Looks similar. When I bought it, I figured it would be a weird variant of a LI or cf but one corner of this hone immediately told me I was wrong about it being novaculite

I have one like that. Was never 100% sure it was an LI
Very find finisher, but not as fine as my CF

Found a better picture. We were never really sure of the ID either. Cool stone whatever it is.

Aah, same stuff. It appears to be slate. Iron loaded is my guess going by the colors. It seems like it would be better with oil, lather, glycerin mix or some other water soluble mix given the hardness. What did you guys use as the buffer? I finally got one side flat and am truing the back as I hate lopsided hones in hand.

There is where I stand with mine. I have one side flat but I need to tidy up one long edge, back I need to just lap out that crater and get a flat track.

I had good success with original ivory dish soap (like half a drop) and water. You can't get it anymore so last times I honed on it it was running water in the sink. I should take it for another spin with some new lubricants and see if it improves

Looks like a Lynn Idwal, Smiths honing solution would help. :D
I have a couple similar in appearance, nice stones.

I'm going to throw in another vote for LI. It has some similar characteristics to mine.

Mikael what about polishing properties ? Can you reach comparble results like a 10k synth stone with only some small scratches compared tonthe synth?

Would you id youre stone more towards a slate then a novaculite ?

Is there even something from the LI quarries that is slate or shale vs the steely novaculite material?

Well its been a while since I used it. But I think that it was pretty fine. I don't know about the novaculite thing. It didn't feel like an Arkansas. But that doesn't mean a lot. Some of the charnley forest hones doesn't feel like novaculite to me either. So take that with a grain of salt.

The shave off of this stone was really exceptionally smooth. It doesn't have that really live top end sharp some finishers do but it was more than adequate.

And if you read a bit more about LI and Grecian hone then you will have it.

Actually those details are not clear for me and i think for others too. there is still no Terminus or research on a Grecian, the information is much less then whats available on LI stones....all what we have are kind of labelled stones where probably some people tried to compare other stones with theirs....or with the stones from the quarries.

Till today i dont found/read any proper information based on a reliable research....

Well guys the hone is mine [emoji4] it's not a novaculite. It's harder then most slate hones and does look a bit like a raw coticule. It is however a slate. When I lapped it, it was very hard and the dust almost white.

I have added some pictures dry, wet, with slurry and the underside which is skinned, like Mikael said.

It could be the legendary Cutlers Green, but is properly a kind of Lynn Idwal.

My stone is a slow finisher. It's difficult to guess grit on a natural, but I think around 10K using glycerin, water and plenty of patience.http://uploads.tapatalk-cdn.com/2016...4ffe0ca13e.jpghttp://uploads.tapatalk-cdn.com/2016...6990833de2.jpghttp://uploads.tapatalk-cdn.com/2016...f3c3620991.jpghttp://uploads.tapatalk-cdn.com/2016...0b5d3a01e5.jpghttp://uploads.tapatalk-cdn.com/2016...fe8938cc1d.jpghttp://uploads.tapatalk-cdn.com/2016...1f2310b74d.jpghttp://uploads.tapatalk-cdn.com/2016...b822d6c37c.jpg

It's in line with what I think. The edges off of mine are extremely smooth but not top level sharp. Acceptable though. I don't think it has more to give than I have gotten from it. It's not the worst finisher I have ever used by any measure. Rather smooth and tame vs one that is too hot or overly toothy
