I think micro-rusting does the damage here. I oiled a cheap disposable-head razor after every use and the blades were still sharp enough over a year later when the rubber/silicone flex point (hinge?) fell apart.
Sneaky bastards had to specifically add in that part that was vulnerable to oil.
Hair is pretty tough, just see how easily it dulls steel blades
This genuinely just improved my outlook on buying new blades
