Here's a pretty guesome story about reusing arrows. Friend of mine was turkey bow hunting using carbon fiber arrows I believe. He recovered and arrow and he put it back in his quiver. Next time he went bow hunting he used the same arrow and once he released the bow string to fire the arrow it exploded and went through his hand holding the bow, left hundreds of shards in his wrist & hand. He had to have multiple surgeries to remove all the shards, took a long time for the feeling to come back and the nerves to grow back. Could've been a fluke, but more likely using an arrow multiple time compromises its integrity.
There’s a joke to be made about not using critical fumble tables, but I don’t want to make light of what happened to your friend, that sounds awful.
