Minecraft wiki entry for Combat, associated text: The primary weapon is the most versatile to use. A sword's damage varies on material and a rule of thumb is the rarer the material, the stronger the sword (with the exception of gold). A sword deals far more damage than by hand, and will greatly increase a player's chance of survival upon being faced with hostile mobs. Even the wooden sword, the lowest tier of sword, deals four times as much damage as the fist (and each further increase in material increases the damage of the sword by half a heart). Swords may also deal sweeping attacks capable of splash damage when the attack bar is full, making short work of grouped mobs. A sword, like many of the weapons mentioned here, has a limited amount of uses, and disappears when its uses reach zero. Again, the higher tier the sword is, the more uses it has, and each tier approximately doubles the uses that a sword possesses, apart from the diamond, which has more than 5 times the number of uses as iron. Enchanting the sword can also greatly increase its power.
