Primitive Spear
This is a double sided spear tutorial which could save your life. It can be used to fish, hunt, and protect.
Material
All you need is a knife and cord (shoelace paracord ....) and some wilderness
Finding a Tree
You want a straight tree that fits comfortably in your hands. It can be small or big as you want. Then cut it to the length of your spear
Splitting
You want to stick your knife right on the top of your tree stick thing. And then hit it with a rock to split it down the middle until you reach the length in the picture
Fixing the Blades in the Place
Find a small stick and cut it into a stick slightly bigger than your spear and stick it down the split to keep the blades separate
Getting It Stronger
Now you want to wrap the cord around the stick all around to get it to stay and then tie it
Sharpening
Now you want to just sharpen both the ends until there as desired
Finished
Now go and hunt or spear fish
