Minecraft has all kinds of enchantments you can apply to weapons, tools, and armor. Sharpness is one such enchantment that can be used on swords and axes.

The Lightning Rod in Minecraft is made from Copper, and ensures that all nearby lightning hits the rod instead of the landscape.

In Minecraft, you can use copper for construction, or for crafting lightning rods and spyglasses. But over time, copper blocks change color.
