The 400-series stainless (the ones that good stainless cutlery is made from) will rust if allowed to remain moist (or in a moist environment). Just much less than a carbon-steel blade of similar hardness.NonEntity said:It's Solingen steel, but not exactly stainless, as the blade will develop a bit of rust on the surface if left in the moisture of the bathroom unprotected, so I long ago learned to put a thin coat of gun oil on, since I rarely use the razor.
As far as a current source, I would still start with your barber. At least you can ask if his/her suppliers still carry them.
