Kylies and various hunting throwing sticks have been around since at least the Neolithic age. They were also used only for hunting small game (rabbits, birds, and the like), being ineffective at killing larger prey at anything further than point blank range.
I'm curious about whether one could make an effective kylie out of metal, and add sharp edges and penetrating points to the airfoil design without impairing its ability to fly level and straight (the primary attribute of a throwing stick made for hunting). Barring an all metal design, perhaps a primarily wooden form with the addition of low profile blades/points would work.
I find the concept of a weapon capable of stable, level flight and the ability to deliver effective lethal force at 50+ meters to be very appealing.
Does anyone have any experience or input they would like to share?

I'm familiar with African throwing blades like this, and I have never seen any reason to believe they have an airfoil design like hunting sticks do.

There may be a problem when throwing something with an air foil. As this device more or less to what you are thinking travels it is spinning, and probably counter clockwise depending and let’s assume it is. The right side will be passing air faster than the left side thereby creating more lift causing the right side to start raising. At that point whatever will start a left hand turn. Thought I’d throw that out there as food for thought. We had a chap on another forum that wanted to make a boomerang with an air foil and kept us posted with his progress and this was one of the first things he encountered. I had suggested early on and after frustration he decided to give my idea a go. It’s simple enough, make a symmetrical air foil, top and bottom. It worked, at least to the point he was happy and the range extended. It seems like he was finally getting 75’ but it’s been too long ago for me to remember the details.

www.throwsticks.com/This site carries reproduction kylies, and has some demonstration videos showing how the airfoil design allows them to fly straight and level over a long distance.

I'm familiar with African throwing blades like this, and I have never seen any reason to believe they have an airfoil design like hunting sticks do. At least some of them do. The only one I have has a cross-section that's flat on the right-hand side, so aerodynamic for right-handed forearm throwing (like a typical boomerang). An airfoil cross-section isn't necessary, but it certainly helps (the Cold Steel polypropylene boomerang has a symmetric cross section and lousy range as a result, but it still generates lift given suitable angle of attack). For a nice sharp aerodynamic throwing weapon, the chakram:

I'm bumping this topic to see if any of the newer members have an aeronautical engineering bent, and/or an interest in getting a metal or composite with metal edges/points to perform like a kylie boomerang, or other stably flying hunting stick. Bonus points if the design is powerful enough to take down something deer-sized (or larger). I'm linking these guys again for their successes in the medium of polycarbonate. THROWSTICKS.com

Not sure adding blades would work as you couldn't really guarantee that it would hit on the right angle. As far as I'm aware the heavier hunting boomerangs were used to break legs, they'd be thrown into the middle of a mob of kangaroos not far above the ground, any injured kangaroo was then killed with club or spear.
