RE: G5 Montec what a broadhead!!!
The easiest way I have found to get them sharp is using the diamond stone. Make sure you use plenty of water and start off with the course side doing several passes evenly on each side with a fair amount of downward pressure. Then repeat with light pressure. After than flip the stone over to the fine side and do the same thing your last pass should be very light pressure and they will get sharp enought to shave hair with. Like mentioned before I dont think you will ever get them as sharp as the stiker, but the blades on the montec are much thicher and will out last a striker hands down. I shot a doe the night before last with my montecs and she went all of about 60 yards.
