I don't think they care. I have met a couple of people who couldn't have cared less how good of an edge I put on their new razors.
One guy actually asked me to dull his new razor, I was a little hurt at that one lol

Caveat Emptor: the commercial principle that the buyer is responsible for making sure that goods bought are of a reasonable quality, unless the seller is offering a guarantee of their quality. Stinks, but it's out there. Now I'm worried about the used razors I've purchased. Is there any such thing as a temper tester? Thank you epd for the heads up!!

No.

Could could do a rockwell hardness test, but where it matters (near the edge) you'd destroy the blade on a full hollow razor. On a wedge you could do it, but given the 'wedge' shape, you'd have a heck of a time getting it mounted in order to be able to perform the test.

Maggard does a great job, that video is worth watching. I think by cooling the blade he is preventing the loss of temper - but I'm no metallurgist.

Yes - temper is lost when you go above a critical temperature range. The blade heats up when buffed, so by continually dipping in icewater you are modulating the temperature to keep it below the critical range. What can happen though without care paid in cooling the blade is that the steel can be quite thin at the edge, so even if the rest of the blade feels cool enough the edge or hollowed part can get too hot.
