1st of all find an old arrow and break It off so It's a foot long and then screw your BH In It and use this when sharpening. You get much better leverage and bite on your the sticks. It will get done much quicker then using just your hand.

Joe- Start close to the top with the BH tip pointing away from you and slowly go down the shaft of the stick pulling It towards you as well. Work on one side of the head for a good 15 to 20 strokes and then turn It and go to the next side of the head. Keep repeating until your happy with the edge. Some of the edges will sharpen quicker then the others. Some of the edge's may take a little more attention then the others.
