I'm ignorant on this subject, so, just for grins, I asked the internet about this. Having carefully read what you wrote, I asked in a way that reflects what I think a good number of people would have understood what you wrote to mean. So, I asked like this: "did native americans make the metal used tor their arrow tips?"
The internet said no. It provided some detail:
"Native Americans did not traditionally make the metal used for their arrow tips. Instead, they repurposed worn-out metal trade items, such as brass kettles and pots, to create distinctive arrowheads known as "Kettle Points." These arrowheads were later replaced with purpose-made iron arrowheads. The transition to metal arrowheads occurred after contact with Europeans, who introduced new materials like iron and brass. By the 1850s, most Native American tribes had lost the knowledge of making stone points, relying instead on metal points from traders."
Like I said, I carefully read what you wrote. I'm not trying to be super critical, because you were replying to a statement that did not say they developed any kind of metallurgy. Very sneaky, but you and I both know that you could have written that much more clearly, more comprehensively. So let's face it, a lie of omission is a plain lie nonetheless.
