Yeah, I might be a bit off when it comes to kitchen knives.
My experience in sharpening comes mainly from straight razors and I would not want to shave off a 5-8K stone.

I tried for months to get my straights as sharp as a cheap Gillette...to no avail. I had expensive, proven stones, compounds, leathers...on and on, spent cash...watched videos from all the honing pro's, honed with different slurry thicknesses, pressures, strops, etc, etc...still couldn't get it as sharp as a cheap Gillette, so I threw in the towel. However, I did take what sharpening experience I had with straights into kitchen knives, and I'm glad for that.
If I ran a sharpening school, my students would have to learn to sharpen straights first (up to Gillette sharpness)...then down to lesser demanding things, such as knives.
Razor guys are at the top of the sharpening food chain, imo.
+1 to Rick and Mel.
I touch knives up on an 8k til they need thinning, the edge itself doesn't change (if your using a consistent angle), so there's no need to grind a ton of metal away. Depending on how expensive the knife is and what kind of workmanship it has, tells me whether I even want to try thinning it, or if it needs to be sent to the maker to be properly thinned and restored. If your knife has no Shinogi, then thinning isn't a big deal. Plain Kurouchi knives I have no problem with thinning Japanese style.
Progression is all about what and why.
