Do you have any AUS-8 knives? If so, how do you find sharpening them?
I re-profiled a brand-new Ultratech which is AUS-8. It was the first time I've worked with this steel.
Not Aus8 but some S30V which are probably as difficult to sharpen or re profile as Aus 8 depending on it's Rockwell hardness (say 57-58)
Must have taken some time to re profile your blade !? .I re profiled a 420 from 25 degrees to 17 and it was reasonably quick but I hear these harder steels are difficult.I use a Lansky system to sharpen ...not sure I know what vice/jaws/system your using there but it looks pretty slick.Is that the knife after re-profiling...looks like about 25 degrees in the photo
