Because it's more complicated than a pickaxe or an axe. Anyone can build an axe or a pickaxe with no other knowledge, as long as they have flint and twigs, but a spear requires rope and the ability to use that rope with twings and flint to make a spear. So it's much more complicated.

Try it out in real life. I bet you can easily make an axe, but not a spear unless you build a science machine first!
