Kinikakos or an arrowhead are projectile points that are hafted (secured) to the tip of a spear, dart, or arrow. Projectile points can be made of stone, bone, or metal, but the projectile point shown is made from stone. Archaeologists look at the characteristics of the projectile point, including rock type, shape, and size, to give information about the people who made it, where it was made, what was hunted, and sometimes how long ago it was used.
The creation of these points was typically a male activity, as it was the men's role to hunt. These tools would be made as needed, throughout the year so long as they had access to workable material. If men were planning on going on a hunt, they would construct many projectile points. These tools could be carried around as they were small. Today, archaeologists find broken points that got lost a long time ago.
