While polishing certainly removes material, I don’t think the tolerances are that tight that it would make a noticeable difference. Usually. Rounding off corners and edges probably won’t change the actual blade geometry and how it contacts the face and if you think about how much variability there is in how a user wields the tool it would be surprising to get a significant degradation or improvement.
That said, I’m sure it can happen and the users’ perception is what counts. I’ve always wondered whether cera-coating can change the geometry. I bought a coated Gillette Tech from Delta Echo a number of years ago and it’s a nice looking razor but it bites. Nasty thing I’ve only used once. Now I have no idea if that’s a result of the added coating material or the fact that he coated used razors that may have been dropped or otherwise abused such that a mild razor changed into a biter regardless of the coating.
In the case of the Rockwell 6s, I have an early model in the silver gray colour and a newer one in the black coating. While they’re both super smooth, the black one is slightly smoother in opinion. Whether that’s a consequence of my imagination, the coating or wear in the molds over time I don’t know. Maybe the later version had newer molds, I don’t know but there it is.
