Interesting... I wonder if they had every been used in mass against cavalry or even infantry and the results. Need to do a bit of research...
I'm skeptical of any claim that any particular weapon is the "best survival weapon" in all circumstances / contexts, and don't endorse that claim in respect of rabbit sticks / hunting boomerangs. I posted the clip to explain how that particular hunting weapon might be useful, and how it works. Without a doubt hunting boomerangs have been used in inter tribal warfare in Australian Aboriginal culture up to relatively recent times. I don't doubt that boomerangs had been used against European settlers during Australia's colonial period.
Oh, I totally agree but it certainly has some huge advantages even over the bow for hunting small game. It's quiet, extremely durable, reusable, good range and a bit forgiving on accuracy.
When I was still in grammar school dad made me some boomerangs out of 1/4" plywood. the school play yard was empty on the weekends so dad showed me how to throw them and after a while I had them flying back to me. I never thought to use them for hunting, but like anything you practice enough with it can become a formattable weapon. You need at least 2 that fly identically so that the first tells you the character of the wind and the second is use for making the hit. If there is no wind that makes it easier throwing strait, but for the returning trick it takes a slight breeze you throw into in a giant arc. I really appreciate the tutorial in carving them, and maybe some day I may whittle a few just for fun.
