Sharpness

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

Usage
$$, Sharpness adds extra damage for the first level, and 0.5 damage for each additional level.

$$, Sharpness adds 1.25 damage for each level.

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

Incompatibilities
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, their effects will stack.

EDIT: It does NOT stack in Bedrock edition because it doesn't allow incompatible enchantments to be used on the same item even with commands, nor can you exceed any levels not normally offered in survival mode for enchants with commands.
