Don't do it!
Somewhere on the net there's a pic of a fella's hand that has a splintered carbon arrow through it. Why take the chance? If the BH is still good just screw it on another shaft and let'r rip.

If I ever get another deer with my bow I'll retire that arrow. One day, I plan on having a collection of arrows that have killed deer for me. So far I onlt have one.[&:]
