If I test my broadheads to see if they are sharp, it dulls them. I think the answer is to sharpen them, but what sharpener to use? I have looked at a "Tru Angle R-3" and Vision Quest's "Real Deal Sharpener". I really don't have a clue. Any suggestions? All I want is one that is simple, affordable, and hones the replaceable blades used on 3-blade muzzies and thunderheads to razor sharpness.
