Thanks for the post, ekretz. It's always nice to hear about someone's honing style on the coti.
I don't think absolutes are very wise in the honing section. Firstly, you are talking about a lot of variables, secondly you're dealing with a practical skill and third, the human psyche.
I have about 25 cotis now. I think they are all different and each requires a slightly/significantly different method of use. One of them, 8x2.5, which was in a rosewood box is interesting. Even rubbing with a slurry stone barely produces any slurry. Almost none. I have to use a diamond plate and even then it's (comparatively) minimal. But I'm sure if I did 100 strokes and looked at it under a microscope there might be at least one floating garnet. Would that be slurry? haha. I'll try and get back to you with the result.
Thanks again for the idea.
