When judging a razor blade, one of the factors for me is the time required to develop rust. I have noticed that some blades I use(d) don't suffer at all (Feather) and others a lot (any by Vidyut). I always thought there is one kind of steel roll used and only the coatings vary, but maybe I assumed wrong. What is your experience?
To limit the number of choices, I have listed blade manufacturers, not specific blades. For reference, here is a manufacturer-blade table with 1 prominent example. If you have noticed only 1 brand of a manufacturer susceptible and the rest made by the same manufacturer rust-free, feel free to mention this in the comments.
