As far as fluting by hand, after building your nipple, put the point on two pieces of leather on your leg, hold it by the SIDES, tilt it to about 60 degrees and smack that sucker. You may want to try a couple of practice swings to get things lined up. The angle is going to vary slightly due to knapping style. Do not hit your corners. Holding by the sides is the important part. If you hit high on your nipple, you'll still break your point, it has to be below centerline. Bill
