Hey all. Well over the past while I've been using a natural finishing stone which is very hard and doesn't give up mud easy. So I've been thinking about picking up a natural nagura. Now, I know when it comes to synthetics I know you use a nagura for just cleaning up the stone, but on naturals I've heard that you use it and don't wash it off but sharpen on it. So I hope that a few of you guys can fill in my gaps and fill me in all the way. Thanks again.
