Picked this up at an antique store today. Rubbing it with a DMT 325 instantly brings up a rich milky slurry. Surface is very smooth. Used it as polishing stage after a pyramid progression with a Norton 4/8. I'm new to this, and have never actually seen a coticule in person, so would appreciate opinions. Thanks in advance.Attachment 84796Attachment 84797Attachment 84798Attachment 84799Attachment 84800
Thats a coticule glued to BBW
Yes -- and it looks like a nice one.
Enjoy...
Lap it (with sand paper) to near flat and
use it like a barber hone once a week and
you will get a lot of good shaves.
I agree its a yellow coticule glued to a shist grit ratting about 4000 with slurry and 8000 with just water. and worth about 125 dollars
You should be very happy using this coticule after a 8k hone. I would suggest you watch for automatic slurry generation when you are using it with water.
If this stone does so (not all do), you will notice that the water becomes cloudy with regular x-strokes. Just rinse the hone and razor every 10 or 20 laps (depending on how much slurry you think is appearing). This will help maintain the progress to an ever keener edge.
(also a good idea to search for slurry dilution threads...)

Very nice hone! Congratulations.
Great stone, you'll like it. Give it a test and show us what you think!
Thanks so much to all for the feedback about this stone. I lapped it with a DMT 325 and used it without slurry to refresh the edge of my 6/8 Dovo Best. Absolutely loved the feel of this stone--so smooth, almost velvety. (First time trying a coticule, very new at this, have only used a Norton 4/8 for a short time.) About 10 light strokes and could see the water turn faintly grey. Followed it with 10 strokes on CrO2/balsa then 30 strokes on leather strop. Very pleased with result, both in sharpness and comfort. Very pleased with this stone!
Still curious about whether this is a combo stone with BBW on the back, or attached to an un-usable schist.
Lap the base or just rub it with wetndri, wet. If the slurry is purple it's BBW...Quote:

I know in the old days they had natural combo coticules and coticules glued to Belgian blue whetstone, they didn't use BBW for honing back then so it was just a backing. Then they switched to concrete at a brief period before Maurice took over for the mine and became Ardennes Coticule. At this point they used Slate to back the Coticules and keep the natural combos for a two-in-one stone. Some current layers are thin and require the BBW and coticule to be a natural combo as seperating them can cause the coticule to break into piece. La Veinette is usually a natural combination stone of the newer coticules.
Nice Christmas present...Great find, looks like a vintage Coti to me, can't be sure though. Do a pic of the reverse side, close up, and wet. We'll tell you if it's bbw, or rub it, purple slurry = bbw....Congrats....
P.S. the fact that the water/slurry turned gray/dark after 10 strokes usually indicates a fast cutting Coti.
