Carbon arrows do not bend or warp like Aluminum arrows do but they can crack & possibly split if put under some extreme sideways bending & if hit something that they shouldn't.

I allways check my arrows after each shot to be sure of no damage especially if other arrows hit any of them, just hold it by the tip area& nock area "about 2 inches away from each is fine" & bend them slightly, you should get about a 25* bend out & still not feel, hear or see any cracking, do this along the planes of each vane & if you do not feel, hear or see any cracking then that arrow is fine.

I've been shooting the same hunting arrows "the ones that I use for my target practice" for almost 3 years & outside of the ones that have been damaged one way or another they all still shoot exactly the same.
