How to make disposable razors last for months

The theory is that razors go bad not from use, but due to microscopic rusting and pitting from being wet after use. I've been doing this for years, and my disposable razors last for 2-3 months.

1. When done with your razor, grab a dry corner of a towel between your thumb and fingers. 
2. Roll your hand over so the towel is upwards, held securely by your thumb. 
3. Swipe the razor on the towel three times, away from the direction of the blades (if you go the other way you'll try to shave your towel), pressing down firmly. 

That's it! Keep your razor where it won't get wet accidentally, dry it each time you use it, and enjoy the savings on razors and reduction in bleeding.
