I was wondering if their is a sharpener out there that you can use on a muzzy style broadhead. I know you can just replace the blades, but when you dull one up a little taking it in and out of your quiver foam and ;you want to touch it up a little, it seems cheaper than buying replacement blades just for that. I would like one that you could use on the 3 blade muzzy's and the trocar tip and maybe a g5 montec head as well. Any advice on what to use or do would be appreciated. Thank you.
