....I am like horse poop..............all over
You would have to be kidding To use a miniscule tip to hit a small bird.
Wide broad tips coupled with large fletching was and still is used for hitting small targets by native people.
It makes no sense to make your chances even smaller of hitting your target.. just the opposite is done.. a large wide blunt...not stone tip is used for that.
It increases the surface area.. upping the chances of a hit and creating more drag to slow down the impact so as not to destroy the target.
No reason to act like you have all the answers.. instead of looking into modern solutions for your artifacts look into archaeological facts and information on native use of items.
Take your own advice Kugar
....and sometimes a stone blunt was affixed to that shaft likely to add addition weight to that shaft which translates into more knetic energy...your free to look into that as well....add to your already vast amount of knowledge......also...answer me why would they use a dime sized scraper....with a stem smaller than a pencil.....any side ways pressure as to scrape would break t immediatly......
