A Refined Knife is a tool item that can be crafted in Stranded Deep.
The refined knife can be used as a stronger version of the stone tool. However, the refined knife is weaker than a pocket knife, but is a good alternative if one does not have access to an extra one; the player is able to cut down trees, harvest plants and use it as a weapon against sharks and marlin. The refined knife is the only item that can skin animals prior to cooking.
- In the current build, like most tools, up to four crude knives can be stored in the same inventory slot, even if they each have varying degrees of durability.
