- Polished and often decorative stones lashed on throwing sticks used in
hurling spears. These stones gave the sticks, or atlatls,
proper balance. Throwing sticks with their stone weights went out
of use in North America around 500 A.D when the bow
and arrow came into use. Banner stones, sometimes termed butterfly
stones, were about five inches in length and weighed from one half to three
quarters of a pound.
