Razor burn or freezer burn?

Check out GreatRazors.com. I am tempted to order from them just to see whether or not they are any better than a regular razor. These razor blades are "cryogenically tempered" at -300 degrees F. That's getting down toward absolute zero. The premise is that the molecular structure changes at that temperature, making it more durable and stable. I found the site because I was looking up fuel economy solutions. I don't remember the exact search string, but a story on this guy came up because he did the same process to his car parts and got significantly better gas mileage and longevity on his car.
