I noticed today that I have a small in one of my arrows by the nock. I was going to use the quick fletch and was wondering if it will be safe to shoot or should I just throw it away.
You could end up spending a lot more than $12 if it fails. Some chances I'll take but I don't think that's one.
Toss it. Google pictures of what happens when an arrow shatters and the slivers go into your arm. It's not worth the risk of a hospital trip.
