Thread: What are different grit hones for?

I recently asked "How many hones do I need to sharpen a straight razor?" I think the better question would be "What does each type of grit hone help with?" I would like to know the purpose of the 1000, 3000, 5000, 8000, 10000, and 12000 so I can decide which ones I should get. I looked at the Wiki page and it said approximately what some of them are for. Is there any more specifics than that? I guess I just have to use my judgement. Your help is very appreciated.

Thanks!
