Another old hunting tool that sounds interesting to me is the bolo (I think that's what it's called). Never tried one personally. Tie a rock to the end of each of three strings. Then tie the other ends of the strings together. So when laid out, it looks like a three-legged star with rocks on the end.

I believe the use is to grab the middle knot where the strings come together. Spin it around your head, and let it go to wrap around and tangle the legs of your prey. Then run over and bash your prey in the head while it's trying to get it's legs free. Sounds pretty brutal in operation, but it might be simpler for a new user to be "accurate enough" to entangle something, rather than having to hit it dead on with a slingshot or throwing sling.

I remember thinking about one of these things back when the Y2K (non)event was coming up. At that time of year we are usually treated to so many migrating geese that you can't walk through the park without doing a line dance trying to avoid all the poop. I figured I might be able to snag a goose dinner with one of those bolo things. You could walk up pretty close to those geese. But alas, all the lights stayed on, so my Neandthal-style goose hunting plans never came to be.
