I assume they used those for hunting , so must have fairly accurate ?The atl-atl projectile is considered a dart.
Those tips appear to be fairly blunt ..thus more foolproof , I suppose .You mean, they ARE fun.
I remember , as a wee lad , my compadres and I modified our rubber suction cup tipped arrows .
Using regular pencil sharpeners , we fashioned sharpened points on the wooden shafts .
Then we played "chicken" . Shooting our arrows as straight upwards into the sky as possible .
The last boy to move from the center circle was the winner .
We wanted to be men !
Brave , courageous and strong .
