I recently got a Chinese 12k from Sparq. I lapped it up to a 1000 grit paper to make sure that it was flat and smooth.

When I finish with my Naniwa 8k, the bevel is very shiny and smooth. Mirror like. When I begin to use the C12K, the bevel looks scratched up and courser than it did with the Naniwa. I am using only water and light pressure.

Am I doing this right? Should I be using slurry? I am just looking to further polish the edge.
