Make sure it actually is BBW. Many coticules (most) have a slate glued backing to support the coti side, which is much softer than BBW and could crack without support.

this one has a slight purple ish color. Is that a BBW?
First look for a straight line between things. Natural combo stones are not perfect on average. Then you will know if they are glued and see what the bottom is for sure.
In general I find that Sheffield steel takes its best edge from a coticule. I have a natural combo and I hone on both sides back and forth ending on the BBW side for some razors but for Sheffield steel, particularly the W&B FBUs I use just the coti side.
Edit: one other thing, try slurrying it with another coti. That may help improve the surface.
The razor you are honing makes a big difference
I use my coti almost exclusively on Sheffield razors,, Most Cotis will produce a comfortable shaving edge on any razor...
However the edge that people brag about is produce with a great Coti applied correctly to the right razor steel ...
Want to crack the garnets ??? put your slurry stone on your Diamond plate (Mine is a 1000) make the slurry on there put both on your base hone and do about 3-5 figure 8's
This will produce a nice misty broken slurry, you can try dilution if you want from there or if it has a very smooth creamy feel you can try a slurry finish see what happens..
These are just things that I use on my Coti, doesn't mean it will work on yours
ps: Only the Vintage Stamps on Vintage Cotis mean anything, the rest is pure unadulterated marketing hype :)
What razor are you trying to hone ???
Pictures would help, you're only sure with a natural combo, and still many variation in there. I use my BBWs pre-Coticule with excellent results, very good pre-finisher ime. But I only have natural combos, so they're mostly good quality.
As to what I said earlier, when Bart, an experienced Coticule honer, honed a razor for me in person on water, I wasn't even that impressed with the edge, being used to an Escher edge.
So I now finish on my Coticules with lather with great results; as said I used (olive) oil before, but that didn't do it for me. But, I just now used some fine machine oil, some sort of mineral oil, and that gave me a killer edge. I much prefer these edges instead of finishing on water. But to each their own, that's just what you gotta find out. Some like Coticule edges on water, some on oil, lather and some absolutely hate them.
Shaving, your skin, steel, etc., as have been mentioned, is so subjective and it's always a trial and error, what works for others, might work for you or it might not. Only one way to find out :D .
A lot of the Coticules I have seen over here (Belgium) that were used by people in the past for razors seemed to have been used with oil.
Sidenote, after severely thinning out my collection I am left with only Heljestrand razors.
But reading how well Sheffield steel reacts to the Coticule, I might re-consider adding one to my collection :hmmm:
Get a Wade & Butcher FBU in nice condition. You won't regret it. Here's my bragging gaggle; just what I have restored (I have many more). The trifecta: wedge, celebrated hollow ground and (factory?) reground
