Cleaving

Cleaving is an enchantment applied to axes that increases melee damage and lengthens shield disabling time. It is exclusive to the Java Edition Combat Tests.

Cleaving adds 1HP + 1HP × level [note 2] of damage and 0.5 seconds (10 game ticks) of shield stunning per level[note 3], for a maximum enchantment level of 3.

These tables detail how much damage is added per level of enchantment, assuming the target is not wearing armor and the attack is fully charged.‌[Java Edition only]
