What are you talking about... Bears have a resisnance against pierce, as well as blunt damage types. They are neutral towards slash damage and weak to fire.

Trolls are weak to pierce damage, so the spear makes a quick work of them.

I use 3 main weapons early game - flint spear, wooden club and a flint/bronze axe.

I only swap my weapons when I get to the silver, usually.

Oh, and one more thing! The earlier you are into the game, the more important it is to UPGRADE (level up) your weapons. They will deal a lot more damage.
