I got some assorted honing stones from a yard sale. Some are labeled with "india" or "arkansas". One says "oil stone". A few of them are double sided, too. For the most part they are not labeled. I have no idea if I should use water or oil or what "india" VS. "Arkansas" really means.
Some of them are very dirty and don't seem like they would cut well without a little TLC.
Does anyone know how to take care of and use these stones, or know of a good resource for learning more about them?
I've only ever had one water stone and have used it for years, but I'm interested in taking sharpening to the next level.
