Sorry to be a little long between posts. I've been out of town for a few days. Now back to the atlatl and dart.
Using the atlatl and dart is easy. Using it well is hard. Much practice is required in order to be accurate with the atlatl.
After you have inserted your wrist through the loop on the atlatl, grip the atlatl firmly by wrapping the thumb and all four fingers around the handle.
Next take the dart in your other hand and fit the projecting point of the atlatl into the socket on the back of the dart.
Now keeping your last three fingers wrapped around the handle of the atlatl, raise your thumb and index finger and use them to pinch a grip on the dart shaft.
You are now ready to throw the dart. Stand with your shoulders square to the target and you left foot forward. Bend your left knee moving you weight over it. Extend your right leg back. Bring your right hand back, maintaining your grip on the atlatl and dart. Sweep the right hand forward trying to keep it parallel with the ground. As you come forward open your thumb and index finger but be sure and keep your grip on the atlatl with your other three fingers. Continue sweeping your right hand forward and follow through as the dart leaves the atlatl.
Did you hit the target? Me either. It takes a lot of practice.
