I've got good mastering of sharpening and honing process on my wood-working tools, but I shave only once a week and am not trusting my strooping capability. For that reason I like the 12k.
Before buying the 12k my stone succession was:
400 restoring only
1000 restoring only
6000
8000 rozsutec with oil
Then 30-50 strops, but I don't feel good with stropping.
After I replaced the rozsutec with the 12k it takes me much less stropping to get shave ready and makes me feel more confident on the result.
