I'm going to have to asked you to stay tuned, we're still in the middle of doing experiments. It's promising, but nothing more.
We decided not the share methods that might not work, and just reflect bad upon the abilities of Coticules in general.
The methods that are presented in the Coticule Sharpening Academy all work very well. If there are future additions to be made, it will not go unnoticed.
There are no hybrid Coticules.
The "Les Latneuses" layer is naturally bonded to a very weird looking sort of rock, that looks like a Coticule with some molten BBW mixed in. It behaves like a Coticule, resembling the "La Grise" layer somehow. Here's a picture, showing both sides of the same hone.
I thought you were referring to a mixture of Coticule and BBW slurry, which is referred to as "hybrid" slurry. A few seasoned members are currently playing around with it in the researchers lab. It's not a secret, but we're not about to make claims about something that may not work with any consistency.
