Thread: Help Please , what kind of hone is this?

I just recently both a hone and have no idea what is it.
It is very light (weight) hone , cuts extremely well and fast.It is hard stone and gives very very keen edge. The grid is about 6K-8K.

Thank you guys.

Hhhhhmmmmmm, is not easy, I suggest to post some pics with whet surface, maybe can help .
I think to have one too, but I've not idea of what kind of stone is. I think is one kind of UK stones.
Regards

I dont know what it is but measurements might assist some of the experts form an opinion.

It is very hard to figure it out from above pics.
Try put pics without color changes etc.
Are you sure it is hard stone and 6-8k level?

Can you show more pictures. Especialy if there are any cracks or other damage. What is the true colour? What colour is the slurry? The grit you have mentioned is "educated estimate" or just guess?

The true color is light greenish -gray , the size is 7 3/4 x 1 1/2 x 3/4 , the grit I would say this :
dull shinny finish , no lines under 70x magnification with slurry. Bevel set flat to the base of microscope.Cuts very nice wide angle(wide V). There is no cracks , some nicks from previous owner seems to me like he was dulling the edge first . It is hard stone I can feel it with my 1200 atoma. Slurry color is light brownish. Heavy drinker , absorb water very quick.

Here we have some more pics

Just a SWAG.Scientific Wild A** Guess! I have found a couple with similar cuts which were used for sickle and scythe sharpening and the length and width would be the same. One is a fast cutter at about 1-3k and the other is about 4-5K. They are found usually pretty scruffy and slimey looking and could be Thuringian or other slate type of hone. Keep on looking in the type of places you found these! They allow a nice long stroke if you get one that does not have some rocks in it to destroy an edge!
You will notice that I left some marks on the lighter one that were a lot deeper before lapping. If the side looks a little like it has a wood grain, layers, it may be a Hindostan.

Nearly had for you diagnosis of Llyn Idwal BUT LI is not heavy drinker and leaves nore polished/shiny finish.
From the description would only guess something towards fine sandstone now. Sorry can't help more.

From pics seems like it is coarse stone .May be 4.-5 k level.
