Failure to check your arrows for damage could result in serious injury or death. A good way to check your arrows is to flex them before shooting. Look for any indication of cracks or creases even minor chips out of the shaft can result in unexpected catastrophic failure of the arrow. If you find any damage to your arrow DO NOT SHOOT THE ARROW! SAFELY DISCARD THE ARROW. Carbon arrows are very strong but not indestructible – do not attempt to shoot or repair any arrow that is cracked / chipped / creased in any way.
This risk is that when you shoot an arrow there are such tremendous forces applied to the arrow that even minor looking damage, for example a small chip caused by one arrow striking another on a target face, can result in the arrow snapping the moment you fire the arrow. In some cases this has lead to very very serious injuries to the archer as a short section of snapped arrow is driven through the bow hand of the archer. The video below demonstrates the issue.
So please shoot safe and always check your arrows for any signs of damage and discard them at the first sign of damage.
