Stay Sharp Broadhead Sharpener

[Yellah nocks]

I have struggled for YEARS trying to sharpen Broadheads. I had an original KME many moons ago and had no success. This time around(sold the kme waaaay back also)I want to try this other brand. I see from other posts I am not alone. Broadheads will be Tusker Spirit screw ins double bevel straight edge. The stayshap model I am looking at is the Model "C" with and adjustable roller.
