Flattened all my Naniwa professional stones tonight use it Diaflat 95 lapping plate for the first time. I did it in the sink under running water like I have seen in videos. Scratches were left in my stones. I found letting the plate “load” up with the waste from the stone towards the end of flattening helped to smooth out the surface somewhat. Should I be concerned about performance of the stone moving forward? Is there something I’m doing wrong? Or am I just worrying about nothing at all? I appreciate any and all advise and comments.
