Glad you did post. Your empirical evidence is very helpful.
I’ve been putting an 8k Naniwa finish and stopping there. I’m staying
with or close to the mfg’s bevels for starters since it was suggested to me
that they know their steels strengths and bevel accordingly. Seemed reasonable to me.
So my thoughts were to fine tune / refine at that angle and see how sharp I could get the knives.
Your post gets me in the ball park and out on the field to play.
Grazie
