Is this the same one as item #121084858923? I ask this because of the old etching I see on the blade. Just doesn't look like the same blade by the rust patters either.

There is a video on Maggards site where he is buffing a razor. He dips the razor in ice water when it gets warm in his hands as he is buffing through different compounds.
The difference is that Brad knows what he is doing...he uses straights & knows how durable, yet fragile they are. There are many who don't know squat about razors except selling and trading them. Again, this is why you have to watch out on auction sites & ask questions. The one I listed above, if you look closely at the pics, is in really bad shape & will have "rust tubes", just like lava tubes, all throughout the razor making it like Swiss Cheese. I wouldn't trade you any regular shaving razor for that one, I don't care what size it is.
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.
