Interesting. I am glad you commented. It's nice getting grounding from someone with a real background in the area.

With that said, if it is a hallucination (and it sounds like it was), it's one of the more interesting ones I have encountered. It almost has the shape of a good idea.

Blade and handle material has certainly changed over the years, but I think good arguments about how relevant that is could be made both ways. They remain handled cutting tools, used in the same general way, for the same general purposes (though as you posted out, some use cases have gone away). Basically anyone from any of these periods would recognize a knife from any other, and be able to pick it up and make immediate use of it for all their normal knife related purposes.

To be clear though, I am now siding with the clankers and arguing for a hallucination. It's an interesting thing to think about, but it sounds like it's not an established concept in any way shape or form.
