I use about 3 different grade of stones, coarse to fine. At this point you could probably skip the coarse stone. Take the insert out. Lay them on the bevel and push them away from you. Make sure you're riding the bevel. You can feel it. do some licks on both asides and flip it over. After I'm done with the finest stone, I'll strop them on cardboard and finally a leather belt. There is no such thing as a broadhead being too sharp.
