I have never done this coticule+ bbw and then again coticule progression.I was talking with understanding how stone should act in scientific way.
Now i do have bunch of coticules +bbw will go and test it.After i have done couple testes i will let you know what i think.
So far my mind tells me it shouldn't work but no one knows how it will in practice.Lets hope Bart's idea is right.
May be that is why i don't like coticule's because i never able to get a good sharp shave ready edge after using it.
i must finish it up on escher's ,Nakayama etc.
