In TerraFirmaCraft, the first things you can obtain are sticks, twigs, and loose rocks. They can be found in almost every climate, lying scattered on the ground. Right Click or break these to pick them up.
Multiblock
A smattering of common sticks and stones.
In addition to gathering sticks and twigs on the ground, sticks can also be obtained by breaking leaves with your fist. Once you have a number of rocks and sticks, you are ready to start Knapping. Knapping is a process where two rocks are hit together, to form a particular shape. In order to knap, first hold at least two rocks in your hand, then right click in the air, which will open up the Knapping Interface.
The Knapping Interface.
In order to knap a particular item, you want to remove squares until you form the desired pattern. For example, create a knife blade by matching the recipe shown to the right.
Like crafting recipes, the location of the desired pattern doesn't matter for the output, and some recipes have multiple variants that are valid.
A knife blade, crafted from several different rock types.
All stone tool heads can be crafted with a stick or twig to assemble them into a tool.
The stone knife can be used to harvest Straw by breaking plants.
Axes can be used to cut down entire trees, logs and leaves included. However, saplings and sticks will only be obtained if leaves were broken individually.
Shovels can be used to dig soil type blocks. They can also be used to create Paths by using them on Dirt or Grass.
Hoes are useful tools for Farming, but they can also be used to cut down leaves and other plant matter.
Hammers can be used as Crushing weapons, but are more important tools used for Forging.
Finally, a Javelin can be used as a primitive weapon, capable of being thrown at targets, or used as a Piercing weapon.
