I use a work sharp precision knife sharpener thats made like the one Bisch is talking about and just match the original grind as best as I can.Like already stated above,Just use a sharpie to mark bevel and set sharpener up to clean marker off,I would think you could do same with the kme broadhead sharpener.If your running out of adjustment then I dont know what to say...If you need to go taller with it I think I heard someone say they wrapped the roller with tape but IDK if that worked are not...
