Sharpness

Sharpness is an enchantment applied to a sword or axe that increases melee damage.

In Java Edition and Legacy Console Edition, Sharpness adds extra damage for the first level, and 0.5 ( × $1/4$) for each additional level.

In Bedrock Edition, Sharpness adds 1.25 ( + × $1/8$) for each level.

An anvil is required to apply Sharpness V to for wooden, stone, iron, and diamond tools. Golden tools and books can get Sharpness V by enchanting.

Sharpness, Smite, and Bane of Arthropods are mutually exclusive. However, if commands are used to have two or more of these enchantments on the same item, the effects will stack.
