Firstl of all, be careful with that D8C: the 325 grit leaves deep and coarse scratch marks, and without intermediate hone it will take a long time on the D8EE before the last evidence of it is removed. I generally do not use a D8C for razors, unless for lapping hones, and when I need to build an entire new bevel on a razor, due to corrosion or after removing a frown.
I don't know your magnification factor. Seeing an extremely fine saw tooth pattern, the teeth being the same size as the scratch pattern from the hone, is normal, as long as the edge shows no sign of crumbling away. If you see a very small chip missing here and there, that's evidence of the hone knocking parts off the edge. If it are just three or four very small chips along the entire edge of the razor, your face probably won't notice if you polish well on the 12K.
The DMT will smooth out further over time.
Another trick I have used with great success is rubbing a piece of coticule over the DMT, till a slurry was present, and hone on the DMT with a coticule slurry. Perhaps you can do the same trick with your Chinese 12K. In my case, the harshness of the DMT completely dissapeared.. It also smoothed out my DMT to the point where it became a little slower cutting, but also much more gentle to the edge.
Hope this answers your question,
Bart.
