Corner-Notched Point
Corner-notched points have a notch toward the bottom of the arrowhead that held the sinew, or strong muscle tissue, that was used to tie the arrowhead to an arrow. The notch also helped the arrowhead stick inside an animal that was being hunted. These arrowheads were used from 500 to 700 A.D. on the U.S. east coast.
Barbed
These were used more often in battle. The barbs on these arrowheads made removing them more difficult, and pulling them out would make the wound worse. Fighting between Indian tribes changed when trade with the French and Spanish introduced guns into their battles.
Agate Basin
Leaf-shaped Agate Basin arrowheads are named for the Agate Basin region, which stretches from Montana to Mexico. They were used from 10,500 to 800 B.C.
Steel Points
Steel points were made much like stone arrowheads, in similar shapes.
Four-Bevel
A four-bevel arrowhead is a smaller version of a spearhead. These stone arrowheads were sharpened on both ends, so they could be rotated if one tip became damaged.
Clovis Point
Named for the Clovis people who used them, these arrowheads are long and don't resemble the arrowheads we think of today.
Delhi
Delhi arrowheads are long and pointed. They have been found all the way from the top of the United States down to the Gulf of Mexico. Paleontologists believe they are about 3,500 years old.
