A sharp metal hatchet for harvesting wood from trees, stone from rocks, and skin from bodies.
— In-game Description

The Metal Hatchet is much more durable than the Stone Hatchet.

The Metal Hatchet has a much higher rate for getting Wood over Thatch when used on trees and a much higher chance of getting Hide, Keratin, and Chitin from dead dinosaurs than a Stone Hatchet or a Pick.

Rarely, a Metal Hatchet can drop as loot from a large dinosaur such as a T-Rex. Be sure to check the inventory of dead dinosaurs before harvesting them, as harvesting will cause the inventory to be lost.
