Some may have this feature on their aluminum arrows and not even know it, but if you remove the broadhead and look down the shaft, some aluminum arrows have a flourescent spiraling all the way down the inside of the shaft. If the arrow is bent at any place, the spiraling will not be even.

The nub on the side of your knock is a good way to feel which way your cock feather is supposed to face when it is dark.

good luck
