Is the unevenness normal for a CRK? This was bought new by me and has never been touched. I was hoping I can just maintain the edge but not sure if that is possible. Should I just put the 220grit on 18 or 20 degrees and start all over?
 
Is the blade flexing in the rubber jaws?

I noticed this on mine I got bevels that are .010” wider on one side. I’m tempted to yank the rubber out and see if that stiffens up the mounting.
 
From what i've seen many CRK knives have edge angles that increase towards the point, sometimes quite a bit.
Based on footage of their sharpening process by hand on a belt this is the result of their sharpener lifting the blade too much when he approaches the point area, and sometimes i also see a lack of symmetry between the bevels on both sides of the blade.
As the knife owner then later tries to resharpen the knife in a clamped system this becomes very obvious.

After measuring the existing bevel angles all along the edge i resharpen Sebenza's etc freehand on Paper Wheels, so i can follow those changing bevels, and when the blade grinds are not too thick behind the edge i can even reprofile them a bit.
Examples are in the large Paper Wheels thread.
