Oiling the blade...

Should you apply oil to the blade of your razor after every use if you use it at least every other day or don't worry unless you are going to have at least a few days rest per blade? I don't want to use any oil unwisely. Thanks for your time and God Bless!:shrug:

if you don't want to use any oil, then don't.
as long as the razor is dry it's not going to rust.
if you have a particularly bad humidity problem, you already know the answer.
