The Lumberjack mod adds 5 new axes ranging from wood to diamond that can take down an entire tree with one cut including the leaves.
The axes also have an added feature that can take down an entire forest if you hold down shift while cutting. The range of trees can be set in the config file where you can also choose to cut out the leaves or leave them intact.
So in a matter of seconds you can take out every tree that stands in your way with ease!
These axes also work on any type of wood and not just trees. This could be a risky move depending on how many wood blocks are in your range but the axes can completely demolish a house with a single chop!
