The general "minimal" tempering temperature for a steel which has already undergone its hardening (austenitizing) heat treat phase is 300 degrees F.
There is no blade I've ever made that would be harmed by 300 degrees F after completion. Handles and fittings would be a seperate issue.
The best I would suggest for your blade is to use steel wool and oil and not mess with cold blueing on a knife intended to cut what will become food unless your diet is seriously deficiant in selenium dioxide.
