Howdy all,

I was looking recently at the Belgian brotherood page and saw how there are so many different colours that cotis come in.

I was wondering if any particular colour would be considered finer or coarser than others.

I know there are also many variables such as hardness or softness of stone. How wet you have it or how thick of a slurry you create. But what about the variable of the slurry stone?

For example I have two yellow cotis, one is soft but the other feels much harder during honeing. Also one slurry stone is a green colour while the other is patchy pink(like a yellow and pinkish cow)

Which combo of stone and slurry stone would theoretically give me the best possible edge?
