Coonbait, that's a good point.
I had a brand new set of arrows at the range for their first outing and hit the nock on one with another arrow. Ended up breaking a side off the nock along with the wood beneath it.
I very carefully removed the remainder of the nock and using a new nock with mold release in it I molded epoxy to replace/fix the wood. Once it was all cured I popped off the mold nock, glued on a new nock, and took the arrows back to the range for their second outing.
Hit that same arrow again and this time split it from nock to about halfway down the shaft.
Damn it.
