Understood. The thing about it is that after you've accumulated a whole bunch of cheap knives (or tools) and come to realize that none of them actually fit the bill perfectly and still need to buy more, you've simply wasted your money. Trust me, I've been there in my younger days. I know it may sound counter-intuitive, but if you don't have a bunch of spending cash lying around all the time, you cannot afford to buy cheap! Buy a quality item to begin with and therefore buy it only once. In the long run, you save more money that way.
As for the kind of knives our ancestors used, they were pretty darn good in comparison to 99.9% of the Chinese crap we see flooding the market today, actually. They were made out of solid pieces of carbon steel, hammer forged and heat treated accordingly, then sharpened to a lasting razor-sharp edge that could take a beating and come back for more. I've been interested in DIY knife making for some time now and a well executed home made knife is probably one of the best blades you'll ever carry, as long as you care for it (carbon steel's Achilles heel is that it rusts!). Such knives have excellent edge retention, plus the right hardness and flexibility where it matters in a hard working knife. Also, as a rule of thumb, remember that ANYTHING stainless is weakened steel (regardless of price), because of the chromium added to the melted steel to prevent it from rusting. And, as far as stainless steel goes, 440A is one of the worst/cheapest you can get for blade material. If you want strength and performance, you NEED hammer forged carbon steel with a properly done heat treatment. This is what distinguishes the $300 knife from the $10 knife.
The cool thing about DIY knife making is that, with a little practice, you can easily replicate and even exceed the specs of a $300 knife all by yourself, which is what our ancestors did... and it costs VERY little to boot (often times it's just a piece of junkyard steel and some charcoal for your backyard forge, plus a good hammer and a decent anvil). There are plenty of tutorials available out there (YouTube, etc), as well as detailed courses/DIY manuals.
So, contrary to popular modern belief, our ancestors' knives were FAR from sucky...
