Coticule love... show off your rock

So I got the 10" broken in now. It's still an extremely fast stone, with a good but not outstanding coticule edge (appears to have particles ~3x larger than my best coticules from the breaks in the edge under the scope... "bad/difficult" coticules have particles 10-20x larger, an average modern 6-10x and a good modern or avg vintage 3-6x). Very nice stone but not one I'll shave off of regularly (I like a bit keener edge). Probably will keep it around for the easy dilucotting though when the mood takes me.

edit: Just did a slurry comp to compare. Avg particle size ~2-3x larger than my 2 best coti's, max particle size 3-4x larger. This is right on the nose of good/avg for a vintage coticule... very similar to a very good modern La grise/verte.

I have already talked about this vintage coticule here on B&B, but today I got a very kind reply from Maurice (Ardennes Coticule): apparently this hone is of the La Nouvelle Veine kind.

He also wrote that this should be a very good finisher for my razors. It's nice to know what I'm dealing with, and I'm amazed by Maurice's expertise! :001_302:

A bit of background: my girlfriend's grandfather bought this in the Sixties of Seventies for 1.500 italian lire (less than 1 € today, maybe 100-ish € back in the day). It's a barber-sized hone, with a BBW backing.

Weren’t the Burton era coticules virtually seamless as in they really took care in mating the blue and yellow so you couldn’t see the glue? I thought I read somewhere thats how you can tell a Burton era coticule from others.
 
Backing stones can be adventurous as well I have heard. I have another rock backed with autoslurrying la lorraine that could be but I never bothered asking them.
 
Lapping this was bad news... Hardest coti I have come across in a long long time. It took more effort than the Brackett's Brazilian hone yesterday....

Some farm fresh pickens from this weekend. Markets have been slow lately but this is a nice turnaround. A 8” soft ark, a 7” Washita-India combo stone and a 7” coticule. The soft is labeled but sure looks Washita. Don’t normally post B-hones but these two are nice. A Shapleigh Hardware Diamond King in the aluminum case and a Carl Monkhouse C-Mon hone. The C-Mon I believe is from the American Hone Company. It is the dual, this side first, this side second feature and has its directions for use inside the box

"Look what I found"
First wild Coti in a while. A 7x1.5” stone with, what seems to me, has a very clean glue line. Have not used it yet but is on the hard side. Was a bear to lap. Has a nice brown/pink river running thru the surface. The backer has a deep maroon color to it

Anyone have thoughts on this stone? I had questions about the inclusions if they may be harmful but from what I could see at magnification, they're not.

Coticules are odd that way. I have had a few with awful feedback, one in particular had orange, thready inclusions that felt horrible on the stone but it was quite fine. Ended up selling it because I hated that feedback. The clicky one I had ribbed edges apart. It had incredibly tiny pebbles in it. If it's doing no harm, I would just go with the flow and if it just annoys you too much maybe move it along..
 
I got one of my old coticule back for testing this coticule still produces great edge s.


Also picture with the dovo for testing for the same chaps coticule all I can say is really nice

Hello everybody! I want to show the stone from Kenigsberg, mined before 1945. I have never seen such big ones
