Thanks for all the feedback on the subject. I see all of you more experienced guys have your ideas finely tuned. I guess it all boils down to budget. Because what I proposed was a set of 3 stones, basicaly a coarse one, a medium one and a fine one. Of course pastes are a good solution for the final polish...
But what if you had to keep it down to a sort of all-purpose stone (this being a combo or not...)? What would you choose?

I read that coticules might be a good all-purpose stone (patience is required, of course...)... By the way, this is the hone I've been considering: NEW! Belgian razor hones
Tell me what you think. Is this a good hone for what I propose? Is it blue or yellow? Finer kind or coarser kind?

Thanks for the replies!
