Stone Knife

Main article: Rock

Unlike most stone tools, stone knives have the same durability regardless of the type of stone used to make them. Stone Knives can only be crafted with a stick as the handle.

Metal Knife

Metal Knives can only be made from tool metals. They can be cast in ceramic molds, or worked on a metal anvil.


Main article: Casting

Bismuth Bronze, Black Bronze, Bronze, and Copper Knives can be cast using a Vessel or a Ceramic Mold instead of working on an anvil.

Place an empty or partially filled Knife mold into the slot to fill it with metal from the vessel. It takes 100 units of metal to completely fill an empty Ceramic Mold. The text in the vessel's GUI will be updated to show the amount of metal remaining in the vessel.

Main article: Working

Knife Blades can also be crafted by using ingots on an anvil with a hammer. This is the only option for higher tier metals that cannot be cast. The durability depends both on the metal used and the skill of the smith forging the tool.

Knives can be utilized as a weak melee weapon inflicing piercing damage, though their best use is in a crafting table to remove decay, process cereal crops, cut food into smaller pieces, and scrape sheepskin and soaked hide. Knives are also used to collect straw from tall grass, to create a meal prep area, to shear sheep, and to open the leather working interface.

Raw Hide will drop as well.

Scraped Hide

When a Soaked Hide is placed on a Leather Rack, a knife is used to scrape it and produce a Scraped Hide.

  • If the output slot is shift-clicked while splitting food, it will result in each piece having a weight of half the one before it. For example: Splitting a 160 oz piece of food with shift-click will result in an 80 oz piece, a 40 oz piece, a 20 oz piece, a 10 oz piece, a 5 oz piece, etc.
