Ever since I've read this I now check my arrows according to Gold Tip's recommendations.
Flex It First
Always inspect each arrow for damage before each shot. Proper care of graphite arrows can ensure years of quality performance. However, shafts can be damaged. To inspect the arrow, hold it on both ends and flex it away from yourself and others while visibly and audibly checking for splinters, cracks or nicks. Rotate and repeat this inspection four to five times. If you find the arrow to be damaged in any way, destroy it immediately. Shooting damaged graphite arrows can result in arrow failure and possible bodily injury.
