So, this is just the initial shaping? Nothing to do with honing the edge?
Sort of. I think the initial shaping is done before the steel is hardened and this looks like the final grinding that happens after that but before the the edge is honed. And it all sort of has to do with honing the edge as you'd have to remove waaaay more metal on the stones if there was no hollowing done, even a near wedge has a bit.
I can't believe anything was accomplished before CNC ;-) Such an elegant design. It is obviously "the right way". Thanks for the link.
I knew about Ern razors and of the machine, but had not seen one in action. Very cool!
Ha ya, how did we manage? Especially amazing is pre-integrated-circuits, I fear few in the future will look back and marvel at the crazy machines that mixed analog electronics with clockwork, vacuum, pneumatic, hydraulic. Yet somehow it worked and there were cameras and airplanes!? Hopefully we left docs somewhere in case of EMP or w/e and we need to rediscover that stuff in a hurry...

Yep. They're out there. I have no idea how we would find them without modern indexing and search technology, though. Reminds me to visit the Library of Congress again (largest public library in the US).
