This was on Reddit a few months ago. I started running the blade against my arm before and after a shave and not only have I prolonged the life of the blade, but it's actually sharper than a new blade. It really has saved me a ton of money on razor purchases and I feel like I'm sticking it to the man a little also. I'm still using the same blade for over 3 months now.
