A:
This has an interchangeable end so you can use the grinder or the sander. It comes with complete instructions with it. What you are going to do is use a marker to color your insert or the end of your arrow, then lay your arrow on the cutter and rotate your shaft 360 degrees. Make sure there is no marker left. If there is no marker then your done with that arrow.
