As many of you know I don’t shoot 3 blade broadheads so I cant offer much help on sharpening them. But, Steve Angell of Simply Traditional does! Here is a great video Steve did on how to sharpen 3 blade heads.
Steve sells broadheads by Magnus, Grizzly, Ace, and Snuffers at prices that cant be beat! He also sells his amazing hand made strops like you see in the video for 25 bucks! simplytraditional.net. or click on his link in the friends tab! Steve also sells other great hunting products in his online store!
