Ok, I purchased a double sided diamond stone the other day and went to work on some Montecs. I started with 600 grit, then went to 1200, finished with a few passes on the strop with yellow stone on it....the results. The Montec's now shave hair very easily, I am impressed. I don't know why this method works better than the sand paper method of the same grit, but it does. For a test, I held a ziplock sandwich bag between my hands and had my daughter let go of an arrow with a sharpened montec on the end. The results of the impromptu test was the arrow sticking in the book on the floor I used for a stop, these heads now cut with ease. I am anxious to give them a try on game....hopefully I can find an elk before the end of the month.
