Also the Mongols were an ‘Iron Age +’ people, the American Indian - Comanche in this case were a ‘Stone Age’ people.
Note I am assuming neither aside had access to firearms. Also as far as I know no North American tribe smelted metal for weapons.
So Mongols with a easy win.
Do you actually think that the human body knows the difference between a very sharp piece of stone or a very sharp piece of metal?
That stone would not be just as damaging and lethal as metal? Right now in current times they make stone scalpels for specialty work. Because they are sharper than metal scalpels.
Or is your perspective coming from the false premise that an iron age culture is more intelligent than a stone age culture? Native American cultures were a stone age until late because they had no need, and were practical.
Native cultures were nomadic. Foundries, even small ones, take a lot of unnecessary time and labor just to produce a handful of points. And they are static, they cannot be picked up and moved along with them as they moved around.
Common sense logic dictates that it was much more intelligent and practical to use materials that are available laying on the ground everywhere they moved to. With one hours worth of work, and the need for the labor of only one person, they could produce a very fine sharp stone point. They could produce five to ten a day.
Even a small one time use foundry would take several days to build, find and collect ore (which is not just found anywhere like knappable stone), collect fuel, and smelt just enough iron for a handful of points.
Larger repetitive use foundries would require that they stay in one place static and feed it. Which was out of the question for nomadic hunter gathers. They would eat themselves out of house and home.
Why were Inca roads narrow? And not built to facilitate carts? Because they did not have carts, why did they not have carts? Because they were stupid and less intelligent than iron cultures in the old world? No... They never had need or practical use for carts, because they had no beasts of burden large enough to pull a heavy cart available. And the terrain in SA was absolutely horrendous.
They used and accommodated for what they had available in the terrain they were forced to adapt to. Llamas and Alpacas. Before you claim this was unintelligent and backwards stone age, consider that during the Vietnam War the Viet Cong used bicycles to transport up to 400 pounds plus pushed along narrow jungle and mountain trails. It was both practical and brilliant considering the situation they were in.
Point is, practicality should never be confused with backwards lack of intelligence. Sometimes it can actually display higher common sense and intelligence based on need and availability of materials and resources at hand. Need to step back and consider all factual variables in the bigger picture.
