1. You should make a Sandbox mode where you have infinite money and the customers will take any weapon you give them, like a GreatHammer PoleArm!
2. Spear weapon would be made by putting 2 ingots onto the anvil to make a sword blade, then you would bash it until you get a "Spear Head" and then you would put it on a PoleArm.
3. Bow and Arrow weapon would be made by taking the logs in the backyard and switching to a "axe" tool to chop the logs into a couple of sticks so you can then use the "hammer" tool to form it into a bow. and how to make the arrow is to take a stick and by making a arrow head by putting 1 ingot onto the anvil to make a dagger blade, then bash it until you get a arrow head, stick it onto the stick to make a arrow and then give the bow and arrow to the customer.
