Multitools!

Multitools are a new tool type that combines all primary tools (pickaxe, axe, shovel, hoe) into one item to save up on inventory space. To balance this out, multitools have half the durability of all combined tools (or twice the durability of single tool). They come in 4 materials: Netherite, Diamond, Gold, Iron.

Crafting

First step of crafting a multitool is smithing the handle first. Applying a copper ingot to leather in a smithing table will result in a Multitool Handle!

NOTE: For versions 1.20+ use the crafting table instead of the smithing table.

And lastly combining the handle with all the tools or a block of desired material will result in a Multitool!

or

and upgrading from Diamond to Netherite:

Stripping, Deoxidizing, Unwaxing, Pathing and Tilling

Axe right click actions (stripping, deoxidizing and unwaxing) all work with the multitool. Simply right click a log or a copper block to see it in action!

While stading, right clicking a variant of dirt block will use the shovel, creating a path. To till the ground instead, hold shift (or your crouching button) and then right click.
