For the single bevel broadheads you need to use the KME KNIFE SHARPENER, not the KME “broadhead sharpener”. The KME “broadhead sharpener” is designed for double-bevel broadheads and DOES NOT work well with the single-bevel heads.
For anyone ‘sharpening challanged’, the KME knife sharpener is the best thing I’ve seen for single bevel broadheads. There’s just no way to go wrong and Ron offers the best customer support in the business. if you have trouble using his sharpener just call him and he’ll take whatever time it takes to talk you through the process.
