I had a Beman that I bent quite a few years ago. What happened was that it was a winter 3D shoot---very cold--- and the arrows were very hard to pull. What I did was start twisting them to break them loose from the foam. Little did I know that doing so actually twisted the inner layers of the shaft, breaking them loose from the boding agent. Called Beman about it and they told me what I was doing wrong and to use lube on the arrows next time.
So be forewarned that if this is what happened then the carbon layers may have broken loose from each other, severely weakening the shaft. For the price of arrows I would not take the chance of just cutting a little off and installing new inserts unless the arrows are sufficiently long enough to cut at least an inch behind the bend. That may mean removing 3" or more from the overall length.
