I have to put in a plug for these razors at GreatRazors.com. They 'cryogenically temper' standard commercial razor blade by dipping the whole box in liquid nitrogen (?). Sounded sort of bogus to me but I'm not a metallurgist. I bought a small pack anyway and have been sold ever since. Better shaves and the blades last a long, long time.
