Hi there. This may have an obvious answer, but hoping someone can clue me in on the difference between a chrome and an all stainless steel DE razor. I own a Merkur 38c (chrome) and am satisfied enough to purchase another as a gift. But also considering the Feather All Stainless. The latter is considerably more expensive but I want something that will truly last for many years. Does the chrome eventually corrode or what? All suggestions & advice welcome. Thanks.
