Arrowheads are pointed tips that are attached to arrows, which are used in archery and hunting. They are designed to penetrate targets effectively, and their shape can vary based on their intended use. Common materials for arrowheads include stone, metal, and plastic, with historical examples often made from flint or obsidian. Throughout history, different cultures, such as the Native Americans and Ancient Egyptians, have created unique arrowhead designs. These designs often reflect the available materials and the specific hunting or warfare needs of the time. Today, arrowheads are also collected as artifacts and can provide insight into past human activities.
