The ultimate survivor shows you how to eat
Growing up in Fiji, I learned from the old timers how to make a throwing-spear from basically nothing. First, you have to find the right kind of stick. It has to be a straight hard-wood with not too many curves in it... this can take days sometimes. The next step is burning the stick. This enables you to straighten out the curves and also makes the wood stronger. Next you gotta dig out one end of the stick to fit the spokes. This can be a real process. I use a nail a lot, and use it like a chisel, basically taking out one piece at a time. You want to dig about 5 or 6 inches into the stick so the spokes can be snug in there.
Then, find your spokes. They can be from any piece of metal — I just found these from under my house. You want them to be about 16 inches long and a little thicker than pencil. Then you have to file them down — I use a file and a metal handsaw. Make sure you use the handsaw to cut barbs in each spoke. For fish under 10 pounds, you want six spokes.
The final process is winding the line around the spokes and stick. I start with the spokes and gradually work my way up to the stick. I generally use wire for this because it's stronger, but you can also use fishing line. Probably the most important part of the process is insuring you have a tight wind so that when your spear hits a big fish, the spokes hold strong.
This spear came out pretty good and I'm starting to walk the reefs at low tide. Check back in to see what I catch. — Aamion
