I recently tried building an Apache throwing star for the first time. It was one of the first primitive tools that I learned about on this forum. Its sheer simplicity meant that it was something I could gather materials for, construct, and test all in my backyard, so I was convinced to give it a go. Here's a picture of the finished result, along with one of the ill-fated targets!
Since cutting up the trees in my backyard was a no-no, and no pieces of firewood were in the right dimensions, I was forced to settle on a thick vine/root from the vegetation that covers our property wall. I cut off the straightest portions.
The throwing star was very easy to make. I sharpened the edges to a point, whittled down the rough edges as best I could, cut some rough notches in both pieces where they would be lashed together, and then secured the whole thing with some tightly wrapped cord. I skipped using paracord just so I wouldn't have to waste any on a casual experiment. Point to point, the star was approximately 16 inches across both ways. The wood was still pretty soft, so I waited a few days for it to harden. It was nice and resilient at testing time.
My targets. The volleyball net served as a good backdrop and prevented the throwing star from cartwheeling away to the other side of the yard, which happened often when I threw it at the ground targets.
After a few misses and glances, I connected. I was throwing in an overhand fashion at this target.
Another solid hit. The cord is becoming unwrapped here, but the fault lies with me. I thought I would try to salvage the cord afterward so I didn't tie it down thoroughly.
After taking enough beating/pummeling/impaling, the first cardboard target broke and fell to the ground. I then moved onto the watermelon!
Some good hits on the watermelon nemesis!
The watermelon took a lot of frustrating glancing blows
With the watermelon, I was throwing the star in a side-hand fashion (so the star would fly horizontally). I found that throwing overhand would often result in the star landing either too early or late, and it would cartwheel away, well past the target. It was considerably harder connecting with the watermelon than with the cardboard target. Although I'm sure it's been used for both, I would see the Apache throwing star being used in warfare more effectively than being used to hunt game. I surmise that a throwing/rabbit stick would be more appropriate for game acquisition.
To compare the throwing star's damage against that of a throwing stick's, I summoned a slightly curved piece of firewood (I don't have the proper-length wood to build my own throwing sticks, but I'll definitely get my hands on some in the future). When I did manage to connect, the throwing stick substitute hit the target with substantially more force. Here's the target after just a couple solid hits.
