The Axe is a tool composed of a long wooden handle and a large cutting edge, useful for both neutralizing Zombies and for taking down doors and trees. It is a two-handed weapon that has a max damage of 2.5, making it the third strongest tool in the game behind the pistol and the sledgehammer.
The axe has a chance to kill zombies in a single, well-charged hit, making it useful for close-quarter combat. It has the advantage of having a greater damage output and durability compared to other tools, making it a great weapon alongside its uses as a tool. It's disadvantage is that it has a long recovery time between swings, leaving the player vulnerable when surrounded.
It's functions include it being an effective weapon in combat, a tool for breaking down doors (providing 35 damage per swing), and as a harvesting device to cut down trees (also 35 damage) to collect Logs which can be cut with a Saw to create Wood Planks.
Axes are quite rare in the game, but are found most often in storage crates (which are usually in warehouses and storage facilities). The hardware store in West Point is a very good place to pick up a few axes and other useful tools relatively early in the game.
The Axe is also a multi-attack weapon, capable of hitting 2 zombies at a time in a swing.
