Pro tip to everyone using these blades: Pickup a bottle of mineral oil from the drugstore, and fill a small cup about half an inch with it. After you shave, rinse off the blade, blot it dry, and stick it in the mineral oil, so that it's fully submerged. Each blade will last somewhere between 2-5x as long.
Not entirely sure about the mechanism, but I recall hearing the oil slows down oxidation, which is the primary cause of the blade's dulling (it's not, surprisingly, the cutting of the beard hairs).
