Description (From Recipaedia)
A spear is a versatile weapon that can both be thrown and used for melee attacks. When used, it will eventually lose its sharpness and fail. Spears made from better materials will last longer and cause more damage. Thrown spears will stick in soft materials. It may be hard to remove a spear that embedded itself too hard.
Crafting
Requires 3 iron ingots and 2 sticks.
