In all honesty, I'd rather people make their own with a bit of help and its never been easier to do it. Not like back in the 1980s when barely anyone outside of an industrial process knew how to even temper steel, most blacksmiths where dead and buried, there was esoteric historical stuff buried in books in the back of the library and everything had to be done by scratch or experimentation. Most of what I learned back then was from a grandparent and father who was a mechanic and machinist, who where literally some of the very few people around at the time who actually knew how to work with steel.
Theres 1000's of youtube vids, blogs, knife forums, dedicated shops, steel specialists etc which all have valid information on them. A metre or 3ft of 3mm or 3/16ths thick 1075 steel will cost you about $25 delivered to your door, do some stock removal, blowtorch and vegie oil will harden it, you can temper it in a home electric oven. That way people can learn the act of actually making things with their hands to their own requirements, plus learning something like that means you've added something to your survival skill repertoire
