Hatchets have improved attack speed and attack damage when compared
to swords, but have less attack speed and attack damage compared to axes.
This tool can break the same blocks as axes, with the addition of
Cobwebs.
There are multiple enchantments available for Hatchets, two of which
allow for special items to be dropped upon defeating certain mobs.
Ravaging grants additional or increased drops from certain hostile
mobs (and even certain neutral mobs). It also grants Strength when at/under half-health.
Despite the pros of this enchantment, it cannot be applied alongside Quick Step.
Salvaging grants additional or increased drops from certain passive
mobs.
Additionally, there are 4 other enchantments for the hatchet that
might prove useful to you.
Striking essentially replaces the damage enchantments (Sharpness,
Smite, Bane of Arthropods).
Quick Step grants the player Speed when at/under half-health.
Though, this enchantment cannot be used alongside Ravaging.
Rejuvenate heals the player when attacking a mob. This enchantment,
however, cannot be applied alongside Quick Step.
Curse of the Leech acts like the opposite of Rejuvenate, instead
damaging the player when attacking a mob.
