Arrowhead

An arrowhead, also known as a projectile point, is the sharpened tip of an arrow.

It usually makes up the majority of the projectile's mass. This weight is vital because it helps the arrow impact and penetrate a target. While most people think of them as tools for hunting, they can also serve special purposes like signaling. A skilled craftsman who manufactures these points is called an arrowsmith. Even today, modern enthusiasts continue to produce over one million new spear and arrow points every single year.

To function correctly, an arrowhead must be securely attached to an arrow shaft. This process is known as hafting. There are several ways to perform this task. One method involves using a cap that slides snugly over the end of the shaft. Another method uses a socket tang to hold the point in place. Some makers use split-shaft construction, where they split the wooden shaft lengthwise. The point is then inserted into this split and secured using materials like sinew, rope, wire, or a ferrule. In medieval Europe, craftsmen often used hide glue to adhere the heads to the shafts.

Archaeologists study these objects to understand human history. Because the wooden shafts or spears are rarely found with the points, scientists often classify them generally as projectile points. This term covers anything meant to be projected, whether by a bow or by being thrown. The oldest known arrowheads likely date back 74,000 years to Ethiopia. In Sibudu Cave, South Africa, researchers found points from 64,000 years ago.

These ancient points contained traces of blood, bone residue, and plant-based resin glue. Using such glue shows that early humans possessed cognitively demanding behavior to create complex tools.

Different shapes and materials have been used throughout history to meet specific needs. In the Stone Age, people used flintknapped stones, flakes, or sharpened bone. In Louisiana, early Native Americans even used the scales of Alligator gar as arrowheads.

As civilizations progressed, humans began using metal alloys. Different cultures developed unique styles, such as the three-bladed, trilobate, or Scythian arrowheads used by the Achaemenid army. These variations show how humans adapted their technology to the materials and environments available to them.

Modern arrowheads are categorized by their specific functions. Broadheads are designed for hunting and usually feature two to four sharp blades. These blades are meant to create a wide cutting edge to ensure a quick kill. Hunters use two main types: fixed-blade and mechanical. Fixed-blade broadheads keep their blades rigid at all times. Mechanical broadheads are more streamlined during flight, but they deploy their blades upon contact with a target.

Some even use hybrid designs, which combine small fixed blades with longer mechanical ones.

Other specialized points serve different roles in archery. Bodkin points are short, rigid, and have a small cross-section. While some suggest they were made to penetrate armor, they may have also been designed for longer flight or cheaper production. Target points are bullet-shaped and designed to penetrate target butts without causing excessive damage.

Similarly, field points have a distinct shoulder to prevent them from getting stuck in obstacles like tree stumps. For those participating in reenactment combat, safety arrows are used. These often have wide or padded heads to reduce the risk of injury when shooting at armored people.

Understanding arrowheads provides a window into complex human development. Hunting with a bow and arrow requires intricate, multi-staged planning. It involves material collection, tool preparation, and innovative social communication skills. The use of snares in ancient times implies an understanding of the latent energy stored in bent branches. This is the same fundamental principle used in bow construction. By studying these small points, we learn how ancient humans mastered their environment through engineering and social cooperation.
