There are several parts to an arrow. The shaft is the main part of the arrow. all the other parts connect to it. The shafts of today are mostly made of carbon fiber. When the combination is used, it is usually carbon fiber on the outside wrapped around an aluminum core.
How stiff the shaft is, is called the spine. It relates to how much or how little the shaft bends when you put pressure on it. The part of the arrow which is the most function is the arrowhead. These are generally made from a hard material such as metal. Sometimes the shaft of the tip is sharpened and used, but more often arrowheads are separate. Types of arrowheads include Bodkin points, Judo points, broadheads, and blunts.
Fletchings are another part of the arrow which acts as wings. They are located at the rear of the arrow and use a little force to stabilize the arrow while in flight. In other words, they are designed to keep the arrow “on its course.” Fletchings were often made with goose or turkey feathers, but modern fletchings are made with plastic, also called vanes. When bird feathers are used, they must come from the same side of a bird if used on one arrow. This is because there is a small twist in these feathers which makes the arrow turn while in flight, and improves accuracy.
A nock is a part of the arrow located at the very back. It is a notch that keeps the arrow in place on the string when you are drawing the bow. Sometimes nocks are separate pieces of plastic or wood, and sometimes they are slots that are cut into the arrow.
If you are thinking about using arrows for the purpose of hunting, be sure you select the right ones. If you are using a high-performance bow, do not use cheap arrows. By doing this, you will decrease the performance of the bow. The main thing that you should consider when purchasing an arrow for hunting is the spine. There are two types of spine – dynamic and static. The dynamic is related to how much the shaft gives when the arrow is released. Static spine is how resistant to bending the arrow is. After you understand the spine, then you need to take into consideration what type of game you are hunting. For hunting large game, you will need an arrow with a lot of kinetic energy. Smaller animals won’t require such high energy or poundage.
