My guess is he is assuming it was cut with a metal blade, which came from white people.
how can you cut something without a metal kn—Colonizers don't get the blade. They deserve the flat edge of the macuahuitl to the back of the head.

Obsidian is plenty sharp to cut into hide, no?
A sharpened rock is sharp enough to cut hide. Flint and slate are very easy to make sharp knives from.
I am sure, I was just explaining my interpretation of this persons racism.
I think obsidian is not good for cutting a shape like this because it's extremely brittle, though you are right that it's far sharper than would even be required.
I really don't know about this subject but from my limited experience, can't you also just make a superficially similar curved cut using a large number of straight cuts at increasing angles? Basically whittling. The edges of the map are pretty irregular, anyway.
Before the 1800s, the Pawnee mostly used flint tools. Less sharp, but holds an edge better than obsidian. idk if they cut the leather for that map with flint or with a metal blade they traded in, but it seems kinda pointless when the objection is coming from a guy who, unlike pre-Colombian Pawnee, would be miserably trampled to death if he had to hunt bison with flint arrows and without a horse.
You could give this loser a gun and his choice of horse, car, or bike and he'd still probably get owned by the bison
I don't get what the issue is. A flint knife will cut leather just fine.
Even funnier when "geologist" is in his bio lmao
Would flint be effective for cutting long curves like this?
Flint is hella sharp, so I don't see why not. You don't necessarily need specialized tools to cut a circle, practice makes perfect and native americans had a lot of practice on that front.
