Joe --
When it comes to arkansas stones, I've heard conflicting stories from people. Some, like Darrel, say that the stones clog quickly if used without oil. Others have told me that they don't use oil or water and the stone cuts better. Here's a suggestion: once you put oil on the stone, you'll have to use oil forever. So why not try using the stone without oil for a few weeks? Then, if you have clogging problems, you can switch to using oil knowing you at least tried the other method. Remember, this is your only chance, once you put oil on it you must continue using oil. Let us know what happens!
I've used lots of ceramic stones, especially the Spydercos. At first, as suggested, I used water on them. However, I stopped using water, and find they cut much better and quicker. Sure they eventually clog this way, but it takes literally 20 seconds with a brillo pad to get a ceramic stone completely clean. Overall, even factoring in the occasional cleaning, I've found that sharpening with dry ceramic stones is faster than using water on them.
As you can see, Darrel disagrees, and that's a pretty heavyweight opinion. Still, no harm in giving it a try -- it won't hurt the stones, and you may even love the results.
