I bought a Gokumyo 20k, and when out of the box needed a good lapping. I put a DMT325 on it to tidy it up, but scratched it too much IMHO.I mellowed the DMT by doing knives on it to knock the top off the plate. I was honing the Gokumyo 20k and really didn't want to stuff it up. So I bought an Atoma 400.

Can anyone add light to the problems I have outlined? I do firmly believe the Gok 20 should be grid lapped well prior to use. It may take longer than a few figure 8's.

Also, what process if any does the ATOMA 400 require (It's yet to arrive)
