Determining coti speed factor?

The only thing I ever really use my verte slurry stone for is to slurry new things I have no native stone for and I just want a mostly all stone slurry just to see what is doing with it. It's a bit crap for grinding against an actual verte apart from maybe misting a bit of particulate into your water during final polish. I have a real soft spot for super hard, slow cotis. They tend to be glorious for finishing old wedges.

So you can do a "nagura" type progression with different Belgian rubbers on a hard Coti to get where you need to be. That's interesting. Never thought of it that way before.

I don't think I would take it to that descriptive extreme, but you can bend the coti's refinement stage behavior to varying degrees with different slurry stones.

Guys have used naguras on cotis with success if I recall.

I believe we may have identified my problem.... lol

After handling hundreds of Coticules I have come to one conclusion, you don't choose Coticules, Coticules choose you.

So, it seems that somehow I have pi$$ed off an entire subcategory of mineral.......

It is possible, i try`d many times, you need at least a very hard maybe LaVerte, a maching slurry stone (LaVerte or any other very hard and slow one) and a soft Slurry stone with high cutting ability (like La Dressante, La Veinette, La Veille Rouge). You will get different results, but in the end it will be always a coti edge . It is like honing with a hard Jnat only with Botan and Tomo Nagura, well done you got a Jnat edge just like done with DMT/Atoma only or full nagura progression.

I just play around with my slurrys, when it comes to a real task, i choose a Coticule that is hard and fast or a soft and fast one, but never use a slurry stone. The only exceptions are my dead slow LaVerte hones, that i use mainly for just touchups or with a slurry stone (most likely a LaVeilleRouge (nowadays) wich turns them into moderate fast hones on slurry.

Probably not - it's just that some of them have a really twisted sense of humor.
