why are these hybrid Techs so highly sought after?

Generally I prefer aggressive razors and do not collect Techs or Gillettes, but I do have a 1940's 7 O'Clock bakelite Tech and, ha ha, an Ikon Shavecraft Tech.
I've had a #66/#77 NEW which was nice but my favourite Gillette so far is the New Improved which is smooth, weighty and fairly aggressive.

So why are these hybrid Techs so highly sought after?
And why did they plate them with Rhodium?
And how's it going to shave?

All it takes is one well known collector to talk up a razor, a muppet to then overpay and from there the flood gates open. With that said it does have some collectability due to it's unqiue design and short production run but so do other Gillette razors that don't command anywhere near the prices or collector's attentions.

The rhodium plating and set seems to be a special thing for a Christmas set in 1947 and not used again afterwards. This is the only known for now example of when this razor and set was sold formally.

Here is some more proof that the No40 set with the 'hybrid' tech was a one off Christmas special.

Not a mention anywhere in those price sheets of the No40 set.

They’re rare and great shavers. They’re a SB version of the RFB new.

It has way more to do with rarity than “overpaying and muppets”.
