Some broadheads literally can not be sharpened. Or at least I've not had much luck getting them razor sharp. They flex so much it is almost impossible to keep the same angle. The Slick Trick blades and some others can be sharpened. I use a Lansky sharpening kit, the jig along with a fine stone gets it close then simply strop it across leather with the same jig until razor sharp. I sharpened 5 sets of broadheads to a razor edge the other night and have the nicks on my hairless upper hands to prove it. :smile:
