The most common form of arrow consists of a shaft with an arrowhead attached to the front end and with fletchings and a nock attached to the other end. Shafts are typically composed of solid wood, fiberglass, aluminium alloy, carbon fiber, or composite materials. Wooden arrows are prone to warping. Fiberglass arrows are brittle, but can be produced to uniform specifications easily.
Aluminium shafts were a very popular high-performance choice in the latter half of the 20th century due to their straightness, lighter weight, and subsequently higher speed and flatter trajectories. Carbon fiber arrows became popular in the 1990s and are very light, flying even faster and flatter than aluminium arrows. Today, arrows made up of composite materials are the most popular tournament arrows at Olympic Events, especially the Easton X10 and A/C/E.
The arrowhead is the primary functional component of the arrow. Some arrows may simply use a sharpened tip of the solid shaft, but it is far more common for separate arrowheads to be made, usually from metal, stone, or other hard materials. The most commonly used forms are target points, field points, and broad-heads, although there are also other types, such as bodkin, judo, and blunt heads.
