RE: Arrow inspection
I broke an Axis St arrow just last night. I didn't know it was broken until I flex tested it. When I did, it crackled just ever so slightly. A little more pressure caused it to snap just in front of the fletching.
You don't have to bend them too much to find out if they are cracked, but you do want to try and flex it from the very ends as most often the cracks will be towards the ends where the arrows colided. A cracked carbon arrow will definitely make a cracking noise when you flex it.
I'm in the habit of flexing each arrow in two directions right after I pull it out of the target. I just grab it from the nock and the point and flex it with my thumbs
If I have two hit really close together, I'll flex each one in four directions and a little harder than usual.
NOTE: Always bend them away from you and from anything else you don't want to stick sharp carbon fibers in!!!!! LIke your friends, your kids, your dogs, your vegetable garden.....
