How do you know a broadhead is on straight when it has been sharpened. The "point" is not as pointed when you first attached it to the arrow and it spun perfectly, no wobble.
In other words, I attach my broadhead to the insert, apply glue on the insert, push it into the shaft, then spin on a flat surface and hand turn until no wobble. I then shoot it to see if flight is perfect, then sharpen...but when I sharpen, this affects the shape of the broadhead right down to the point. It might fly perfect, yet spin with a wobble?????????
