Apparently, razor blades don’t get dull because of the shaving.
Instead, they get dull because the moisture on the blade from the shaving that causes oxidation, which leads to microscopic rust forming on the blade and causing it to become dull.
Thus, dry them off after each use, and you should be able to make one blade last for much longer than ever before."
