I was going to make a crude joke about the situation being a real hisser (substitute a letter) but seriously if you have blades there that are rare or loved just bathe them in 99.9 rubbing alcohol to kill any bacteria from their brief sojourn in the lavatory, dry them out and they should be fine being stainless.
They should be just fine. However this illustrates the inability of women to understand how men think. My wife is no different. She can have dozens of perfumes and shampoos, but questions why I need more than one razor, blade, soap or after shave. Also - your story is making me rethink the idea of attaching a shelf unit above the toilet to display my equipment. We're all in this together.
Time for a sing along! Everybody... 30 blades in the john, 30 blades in the john! Flush one down, swirl it around, 29 blades in the john!...
