Very Nice finishing stone indeed.

Would you have further information about these hones from Sienne? I've never heard about them before and really would have thought that my hone is a coticule (by how it looks and feels).

yeah i think Tharis means the Pierre Du Sud-Ouest....i behaves a bit like a Thuringian stone and looks like a Coticule.Typically it shows these plant inclustions comparable to the Chalk Stone form Solnhofen (Solnhofer Plattenkalk). Like this Example here



For sure these french stones are different and the german chalk stones are not usable for honing....

I found another example three months back on an Italien Museum Site showing a near Identical Stone like the french ones....These were used as razor hones, so says the description

Here a picture of the Italian Razor Hone:


Here the original Link:
Museo di Storia Naturale dell'Accademia dei Fisiocritici - MUSNAF Siena, Italy-Immagini Marmi Antichi

Here is the original french post:
La mystérieuse "Pierre du sud-ouest"

I dont know if this Italien One resamples the french ones in its full properties, because the french ones mostly look more yellow. Interesting is that in south-east of france they had a lot of guestworkers from Italy and Spain, which was mentioned on the french Board. So it could be that these people brought these stones to france.....but that would have to be proven in detail....

Here is my example:

We went on an investigation during quite a long time without knowing exactly what this stone was, or where it came from.

We though during a time it was a sort of old coticule, but we showed it to Bart from coticule.be and a geologist working with Ardennes coticules, and they told me it was for sure not a coticule.

Then Altus shared with us the document showed up here by Doorsch of this italian stone, and a document was found by CharlieHorlogerie telling that some of those stones were present near Veronne and other places in Italy (and in fact some other slate quarries).

Recently I showed it to M. Maurice from Ardennes Coticules, and he agreed that it was an italian stone (he had a piece of raw stone too).

But there's not that much documentation about it..

Thanks a lot Thaeris and doorsch, that's really fascinating ! So, it seems that I had a rare antique finishing hone without me even knowing ...

I had received it from France as part of a lot with several different hones.

Cheers

Totally Fascinating. Thanks for posting. When I see these great stones, thoughts from a kid on of where I might have seen similar sedimentary rock when out trout fishing in canyons, creeks and rivers or hunting, there are many stones yet to be found and tested.

Check out eBay item #221854346486...
I think you can afford to let them go if they sell for that!

It is nice and big but wow that's expensive

Hi folks,

I still can't believe my luck, I've just received a fantastic specimen of a coticule - a huge 25,5 x 6,2 x 2,8 cm (10 x 2.5 x 1.1 inch) vintage coticule/BBW combination stone (1.3 kg heavy!):





Here in comparison to my 22,5 x 5 cm (9 x 2") Escher and a 17,5 x 4 cm (7 x 1,6") coticule/BBW natural combination stone:


And here with a almost 7/8" (21mm) Sheffield razor for comparison (looks a bit lost on the huge hone ):


The coticule side is perfect , i.e. no cracks, blemishes or discolorations. I can't wait to see how it performs but I guess it will lead to an early retirement of my other coticules ...

Cheers
Jörg

That's a beautiful stone! Congrats!
