What is the term used for the main structural component of the arrow?

The main structural component of an arrow is referred to as the arrow shaft. This component is typically made from materials such as wood, aluminum, or carbon, and it forms the primary body of the arrow. The shaft provides the necessary strength and rigidity to ensure the arrow can withstand the force of being launched from a bow.

Properly understanding the shaft’s role is crucial for hunters and archers since its characteristics (length, weight, and material) significantly affect the arrow's performance, including its speed, accuracy, and trajectory. Other parts of the arrow, like the arrow point (the tip used for penetration), index (referring to the nock that guides the arrow on the bowstring), and vein (fletching that stabilizes the arrow in flight), play important roles, but none serve as the primary structure that supports the whole arrow.
