I do not. Many coticule descriptions that mention a glued on substrate say that it is not suitable for honing. The same may not true for all natural (not glued) coticules.

Ardennes describes it as an unusable honing surface only meant to add support to the yellow coticule. I know a few guys have tried it over the years but the consensus is that it's no good for honing.
The fact that most people won't even use the BBW side of a stone when it is known to be used for knives especially and sold marketed that way by the mine should tell you that a piece deemed unusable by the mine would not be worth the effort even if it actually did anything.
