Are you talking mechanicals or fixed? mech's will stay sharper longer due to being closed and not contacting the foam of the quiver like fixed. I reshoot my GrimReapers after just a touch up to resharpen them and I have several that are going on their 3-4th animal. As was said, if they are fixed, just a LIGHT coating of Vaseline will do the just fine. Take them out of the quiver if caught in a rain andlet dry will help as will the quiver also. That and trees and rocks have a tendancy to shorten the life as well!!!!!!!
