I was originally planning on getting Norton's lapping stone to use on the Norton 4K/8K. I was thinking, if I decide to get another hone that isn't a Norton, wouldn't I have to get a different lapper? So now I just thought of the DMT 325 stone. I was wondering if I could use the DMT 325 on different brands of hones. So if I have a Norton 4K/8K and decide later to get a Naniwa 12K or Shapton 16K, could I use the DMT 325 to lap all of them?
