Pete, It sounds like you are where I was a year ago. I had just ordered a KME sharpening system and still couldn't get broadheads out of the package sharp with it. I learned to use my KME broadhead holder and run the broadhead across a mill bastard file first, then to move over to the stones that came with the system. I can get any broadhead shaving sharp now in just a few minutes. I shot stingers in the past, they come razor sharp out of the package. For all of the dull stingers I have that weren't re-sharpened due to a lack of know how and confidence, I could have purchased a three or four KME systems. I would be happy to show you via video what I do now that works for me.
