I was wondering how to store my Chosera waterstones and DMT diamond plates. Is it OK to just stack them on top of each other? I was concerned that with the heavy DMT plates they might rub against one another and damage the diamond surface. How do you all store your sharpening stones? I called DMT and they said you can just put a paper towel between the plates but it's not really necessary. Are there any other things to do prior to storage? I just rinse them off with water. I am really happy with my sharpening stones and since they are fairly expensive I want to treat them properly.
