I was lapping my new Naniwa 12k and my Norton 4 and 8K stones, in my 4 and 8 Nortons, I have these fine scratches. What did I do?! Did I ruin them? How did this happen? I used the DMT 325 on the Naniwa and first a Norton lapping stone and then the 325 on the Norton, what did I do wrong, please help!
