Thread: Do you know your coticule

Coticule are awesome stones.

Here are mine...the one on left I am not sure it is even a coti but the rest are. Notice the green one. I think it is the water that makes it turn green but not sure. Our water is very hard and lots of menerals. The one on the right is a natural and is one of the best polishers I have...it is very uncomon I think for coti rocks!

Thought I would post the two coticules that I have. First one is a standard grade bout glued to slate, no clue as the vein. Fairly slow on water and the second I thought was a La Petite Blanche cause of the line in the side, but it is glued to BBW and the line is more purple than blue. I am still working out the kinks on this stones, but so far seems to be fairly fast on slurry and water. Also on a side note the slurry stone I think is a La Grosse Blanche since it developed brown spots on it, but it didn't get them till after I used it to create slurry on the BBW side and it took about 30-45min for them to show up. Never got them from the bout or sitting with water on it. Thought I would throw that in there since I read alot of posts about why the spots might form.

I am 100 percent postive your left one
is a coticule.
It might be a more rare cut of coticule stone.
in my opion.
I am not export i just aways shop for them.

I love this thread!! makes me wish I could afford a Coti', but then I'm still have my learning curve with my J-nats

Great collection of rocks fella's, good work!

Glenn,

Just an FYI, your coticule is from the La Nouvelle Veine layer.

I have no clue what vein the Vintage was from and I doubt anyone could honestly nail that down..

The Select is at least 8 years old from Howard at the Perfect Edge originally, it has no inclusions or marks, it doesn't matter how fast it is, I use two different Slurry stones if I ever want to produce a cutting slurry and both are softer than my stone .. I have no clue what Vein it was from I doubt there were vein names when it was mined..
It is very hard and very fine, I use it 99% of the time as a final finisher on Sheffield steel, it comes in after the razor is fully shave ready either on the Norton 8k or the Henckels (naniwa) 8k.. I do about 20 Pigtail strokes with a light slurry made from a dmt 325, and then I dilute out over the next 20-25 X stokes ending up with clear water and light X strokes...

Sometimes when I am having fun I will use the old BBW into Coticule system after a bevel set, using the same light slurry to clear water system I outlined above with both stones.. My BBW is also a 8x3 from Howard...

Well that makes the 4th official guess at which Vein it is from, and the 4th name I have heard, including one from Bart

Perhaps it is rising to its layer of expectation!

It has thin blue lines on the side of the stone in the yellow right? Only La Nouvelle Veine has this....


If it helps, I think they're the best finishing coticules LOL.

Coti is on the list of things I put on the wishlist for the future.
