RookieI agree with the majority on this too!!! I have hunted as much as three times a day--Morning/short break/middle/ break/ afternoon--and using fixed heads slidding in the foam(quiver) has dulled myblades--So after you take it out and put it back in a few times check it(sharpness)--I now use Mech.and my quiver has two grippers so the heads don't touch anything!!GOOD LUCK!!
