For what it's worth, many of my regular rotation razors have what I would call 'minor pitting'. As has been mentioned, in order for a razor to be shave ready, any pitting on the cutting edge must be honed away or it will not shave. When I restore a razor for purposes of shaving, not necessarily collecting, I am only interested in its ability to remove my stubble. I will not waste my time with a highly corroded/pitted blade, but so long as I'm able to stop any active corrosion and the pitting has not compromised the blade, I find that minor pitting can even add 'character' to the razor.

If what you're after is a razor to shave with, a 'shave ready' razor with 'minor pitting' will certainly do the job for you. It may also save you a substantial amount of money over a defect free blade.

Just my opinion,
