I cannot give any better advice than what's already been given, in regard to shave readiness on an 8K Norton.
But,
I noticed that you mentioned, you have "other" things that need sharpening. You probably paid a good penny for that Norton set-up. If you plan on getting the most out of that 4/8 for your razors, then I would keep it for razors only. JMO
I can't even think of touching my 4/8 with anything other than a razor. I have other stones to keep my knives sharp.
