Tuning the Non-Returning Boomerang/Rabbit Stick (NRBs part 4 of 5)

Greetings! In this video we will tune several NRB blanks, while discussing how the decision making process works and how to shape your stick for its best flight!
Names matter, and cultural respect matters. This presents a difficult situation for someone studying thrown stick hunting technology, because there are literally hundreds of language groups that have some contact with this technology. It is further complicated by the fact that in many cultures specific types of NRBs have specific spiritual significance, especially in southwestern North America and Australia. In this video series I am attempting to interpret the the physics and practical application of aerodynamic throwing stick technology and its genuine worldwide scope, but not its spiritual significance. I am using the terms rabbit stick and NRB/boomerang somewhat interchangeably because they are the most commonly used words, but I do recognise and acknowledge that this is an oversimplification. This is not in any way an attempt to extol any culture as superior, or to take away from any culture's importance or validity. Thank you for you patience, and I would to love to hear your thoughts on the importance of your specific tools to your culture if you care to share!

One small note, I had filmed some of this before deciding how many segments to cut it into, so in a couple places I call it the third video instead of the fourth, some of that was editable some not so much--sorry for any confusion!
