I too have spoken to both Rob and his father Maurice Celis, the owner of Ardennes Coticule.
Allow me to quote an email of Maurice:
"Beste Bart,
De korrelgrootte van de BBW is groter: tss 10 en 20 micron voor BBW en tss 5 en 15 micron voor Coticule. De gele stenen slijpen inderdaad fijner maar dat is amper te merken. Ook met een BBW kun je een scheermes slijpen. (...)"
"Dear Bart,
The garnet size of the BBW is bigger: in between 10 and 20 micron for BBW and in between 5 and 15 micron for Coticule. De yellow stones indeed hone finer, but the difference is barely discernible. A BBW is apt to hone a razor. (...)"
I once asked Rob why they gave a grit rating to their stones, which is in my opinion more confusing than helpful. He said it would otherwise be hard to market the hones on the modern market that seems to expects quantifiable numbers.
I agree with Ben.mid that Blueprinciple's integrity is beyond suspicion. I just think the information on the Ardennes Coticules website tries to guide the proper audience to their outstanding products, with offering simplified information. In my posts I was merely trying to elaborate on the finer points about the Belgian tandem. If anyone got the idea that I was criticizing "the Invisible Edge", then I humbly apologize.
Bart.
