I broke down and purchased the KME broad head sharpener standard kit. I must say I am very happy with how fast it worked and the finished quality of the blade when I am done. They are at least as sharp if not sharper than my G5's from the factory. I highly recommend it. I was also told that if my stones ever dish out they will replace them for free. Even a "dumbarse" like me can now sharpen blades and get a "scary" sharp edge. http://www.kmesharp.com/broadhead_detail2.html
