Coticule love... show off your rock

Good looking stone @Ganko , Mine has the characteristics of several different veins. It is nearly impossible to accurately identify the vein of vintage Coti’s. I am just content when I find a vintage hone, it is of a razor finishing quality that delivered a keen, smooth edge
 
These are the two thickest I’ve had. The hybrid stone I gifted to a fellow forum member, it was something like 28mm thick. This one is a small chunk, and In this instance the thickness is justified as it is just “as is” when it was likely a mine offcut

The thickest I currently own is this at 25mm solid coti, it makes no sense to me that this would have been sold as a solid piece.
It seems to be a dressante with part of the upper layer present, it’s a rock hard stone and you’d never wear through 1/4” of it in a lifetime of razor honing. So I can’t fathom why it wouldn’t have been cut into at least 2 slices especially since its a big stone.

As for stone in that video..... it would have made at least 5 good slices!? If that came from ardennes it must have cost a fortune 😂

Here is another small fat boy
Hard and smooth
Very difficult to raise a slurry
Working with this one is a big challenge
But ones you've master your strokes
The razor can easily pass HHT,FHT65,CFT2 and finally FET 1
HAPPY HONING TO ALL

Don’t know about the logo, but that is one of the coolest cotis I’ve ever seen. Every stone should be used, but that logo is so unique...
Beautiful stone, Tim. That logo is a new one to me as well.
A update on the logo. A fellow Coti Connoisseur gave me the info to put the logo to a Company. SPERRY & ALEXANDER: New York City importer located at 30 Warren Street, New York City and active in 1893-1927. I have also found the logo on other items including SR and B-hone from Sperry & Alexander. A tidbit of info to feed us knowledge nerds.

Great video, Tom. That really shows how much time and effort they spent getting these rocks out of the ground and in to our hands. Hats off to the old timers and to the folks at Ardennes for keeping it going today.
 
Man I have been craving a full size coticule (and hunting) forever. Visiting this thread always makes me go "maybe I should grab another small finishing one as well just in case" haha. Almost had one but it slipped away in an auction sadly

The worst was when that one guy was scoring those microtome coticule stones and I couldn't find one :(
 
David , That mine shaft must have been a monumental task in and of itself. The way they layered the rocks too. Near the end when I saw the wall of thick coticules ready to go. WOW just don't see them like that anymore. It does make one wonder just how much of all those big old slabs were used up and how much is still out there waiting to be found again. I have to say no matter how hard the work that would actually be a dream job. I love stuff like that. Sure I would think different after a few years though.
