I took the little blades out of small single bevel ramcat broadheads an used needle nose visegrips to hold them. ran them over my finishing paper wheel with rudge on it an got razer sharp polished finish in no time. I shaved hair with each blade before putting back in the feral. I never sharpened a single bevel before but very easy to do. after finding that out I will be getting some of the helix 2 blade single bevel heads for sure .
