... the guy with the business of treating razor blades, I see that NASCAR (hang on a second now :w) treats their engine parts. Now granted I have my opinions about NASCAR and it's credibility, but if what Robert is saying here is true, then unless the engine parts are either a) all stainless steel, or b) untempered/unquenched carbon steel, then it seems that again this is just a marketing ploy.
I guess I'm left with a feeling that, aside from dipping in liquid N2 being a bad idea, 1) the general consensus is our razors won't really improve at all by slowly being lowered to -300C. 2) there is more to cryogenic treatments than simply lowering the temperature of something for a period of time, and 3) most of this is marketing hype.
There are several steels that will improve from this process. There are a good many metallic items that do improve with cold treatment. None of which are routinely used in manufacturing razors. So, it's going to be money spent on a process which has not been proven to work in those steels. I have yet to see objective data, with the exception of the one author noted above. I remember freezing magnesium engine blocks in Volkswagons and that did have a notable improvement in resistance to wear in the treated parts. But, for the most part, this is money spent on a process that may or may not improve a carbon steel razor blade. Stainless razor blade, you get no argument from me.
