This is crazy! Alpha has been experimenting with a 25 cent razor for the past 3-months. It's still sharp as the day it was unwrapped. Aaron Marino of alpha m. has been implementing a little trick on how to preserve the life of your razor.
The razor gets dull from water residue and condensation left on the blade that oxidizes and creates divots. When you are done using the razor, rinse it off, get all of the hair out, and then use a hair dryer or blow on the blades. Finishing by drying with a towel. You have now saved a ton of money on razors!
