To be honest, I wouldn't do much of anything to this razor. I'd just tighten up the pin a little and maybe put some tung oil on the scales. As far as the blade goes, please do not breadknife the blade. I can't see much, if any frowning in the blade from looking at the pictures. If it is just a slight frown, it could come out with just a little acrobatic honing. Breadknifing is only for the most serious of restores.
