Identify natural hone

I have a natural hone I bought online some time ago (many 2 years) and I don't know what kind it is.
It is a fine hone, I have used it as a finisher even though it is so small... It gives a wonderful edge! and the size is perfect to travel with... :)
It is hard, not as hard to lap as a Tam O'Shanter, but it feels har. And it absorbs a little bit of water, but very little compared to other naturals I have experienced.

The pic has a razor to compare the size to...

When I got it, it was glued to a small paddle strop, but that was old and broke quickly.

Any ideas what it might be?

Thanks,
Jacke

Size wise, it is reminiscent of a Thuringian, but it is quite thin. It might just be worn down, but also, they don't really absorb water.

I dont think it is that much worn down, I think it was mounted on a small "paddle strop" to support it and make up for the thinness.

About the water, I might be misstaken... I had a feeling it absorbed thiny amounts of water, but on more closer observations it might not.

It could be a Swedenstein... the hone on a paddle in one picture here looks like mine used to do, before the paddle broke. But mine is darker than these appear to be...

The previous mounting was a common one for Swedenstine hones. I have one that I love in that format. They are a thin layer when quarried and usually a lighter gray with some streaking and perhaps a slight blush of pink.
Do a search for the name and see if is what you have.

Great minds!?!?

There is a hone that looks like that you can find for sale in NY from time to time. Always in a pile of other ancient stuff. I have a few at this point. Attachment 258762Attachment 258763Attachment 258764Attachment 258765

They're not thuris whatever they are. They don't feel like uk or vermont slates either.

I loathe giving k ratings to naturals but if you put a gun to my head I would say 10ish give or take. Probably take on water alone and a little better on something not water

Mine does polish out N8K and C12K scratches.

I think where it really shines is as the bridge to something especially fine be it from synths or a very average coticule move to this and then to whatever. You can shave off of it just as well though.

I would say mine is higher than 10K, I use it after my Naniwa SS 10K. And it gives a fines edge.

I actually dont know how well mine polish scratches from mine Nss10K, cuz I havent looked at the edge with magnifyer... have one in the mail though:) so Ill have an idea when I can play with that!
But 15-20 laps is what I usually do on it and it gives a smooth shave!

These might be the closest ones in color I have seen. Not the 3d hone though...
Could they be a variant of Schwedensteins?

Not sure. Sebastian has a few as well.

Would vote for Schwedenstein in the case....but can you add some daylight shots ?

What measures ?

I will, first thing in the morning when daylight!

Thanks,
Jacke

Another pic, in daylight:

It measures 1" x 5 5/16 x 1/8
And in mm: 25 x 131 x 3

That is definitely what I have at least on a visual level. Naturals vary obviously. I'll take the bait. I will make a video and upload it.

Another piece of banded material. Banding is on the bottom of this one and bottom is a mess so never lapped it as I hand hone and it is shallow as is.

Jup, this is the same!

Thanks! But the question remains, what stone it is... :)

I don't know. I don't read it as UK material. Since ppl in europe find it from time to time I don't think it is from here in North America either but came over with people. It might be German.

It is a Swedenstein thuringian - a bit coarser and faster that the average thury . They varie also from soft to hard - and they gave surprisingly gooood shaving edge - like a Jnat goood or very fine and goood coti edge - Sharp and smooth

Thanks a lot!

I have a black Schwedenstein Thuringian that does very well. Mine is quite hard, fast with slurry and a pretty smooth finisher.

Not a "Swede" in my opinion.
"Just" a banded slate. But that doesn't say anything about the performance! There are a lot of black slates out there, that are fantastic finishers. In Germany and also many other countries most slates that were mined for building houses, roofs etc. have small abrasive particles like quartz included and are therefore good useabla as a whetstone. Not all are fine enough though but a lot have real good performance as a razor hone.
