The angle marks on the KME don't mean a whole lot since the angle depends on how you mounted the broadhead into the jaws. They are for reference only. What I do is take a marker and mark all the way across the edge of the broadhead. I then take a pass across the edge with a stone to see where the stone is hitting and adjust my angle accordingly. With my Cutthroats, I usually have the angle set around the 24 or 25 degree mark. When I sharpen my Meatheads, that have the same 25 degree bevel, I have to set the angle up to 30 degrees.
