Spears are long sticks with a point usually made of metal, animal bone, or sharpened wood. Spears are good for holding cavalry off, and they can be used with your hand, or thrown. Spears go back to cave man times when they would take tusks or some other sharp bone of animal's body, and then tie it onto a stick about a yard or two in length.
