How do you make weapons in the wild?

Always use branches right off the tree-fallen branches may be rotted. Spears can be made by filing one end of a branch on a flat rock to a point, then harden it with fire. And a 3-4 foot hard branch made as flat as possible (but retaining a 2-5" thickness) can be thrown underhand as a suprisingly effective midrange weapon. If it has a slight bend even better.
