I am an Atlatl maker. I make ancient spear throwing weapons for a living. AMA!
My name is Bob Berg and I have been manufacturing atlatls (spear-throwers) and darts (spears) for nearly 25 years. My business is Thunderbird Atlatl, and we are the world's largest atlatl manufacturer.
The atlatl is a spear-throwing weapon that pre-dates the bow and arrow. Here's a picture of an atlatl.
It consists of two parts: the atlatl, a stick about the length of your arm with a hook on one end and a handle on the other, and the dart, a spear that ranges from 5 to 8 feet in length (1.5 to 2.5 meters). Atlatls were used by the Aztecs, Incas, Mayas, Inuits, Australian Aborigines and countless other cultures around the world. It was actually invented independently many different times throughout history.
Here's a video of me explaining what an atlatl is, and why it's superior to throwing your spear by hand.
Ask me anything!
