Thread: Is this stone is coticule ?

Hi. Is it coticule ? What do you think ? Is it worth buying ?
I now that is hard to judge from the pictures but any opinions welcome.
Thanks.

Yes!!!!!!!!!
It is a glued coticule. Don't worry about the cracks, they generally have no impact on the honing.
If you lap the bottom dark side, you can determine if is a BBW (Belgian Blue Whetsone) by the color of the slurry. If it has a purple tint, it's a BBW. From the apparent age, it almost certainly is BBW. Newer ones use slate.

Lap it, chamfer the edges, and have fun honing!

Edit: Sorry, I did not realize you had not bought it yet.
Is it worth buying? It depends on the price and if/how you intend to use it.

That's a nice Coticule/BBW glued combination with a nice thick Coticule layer. If it's worth buying depends on the price, the value of stones are subjective.

Thanks for replies. One day left. Fingers crossed.

I think that the non-coticule side is slate, not BBW, as usually are mounted the cotis

I disagree. Given its apparent age, the odds are high that it is not slate.

I agree. The odds are very high that the backing is not slate. As Utopian said, lap the non-coticule side, if the slurry's purple, it's BBW.

Maybe you are right I have only seen coticules+BBW in natural combination, the glued coticules that I've seen are always mounted in portuguese slate, because the costs are cheaper than the french or belgian slate.
