Survival Knife (Subnautica)

The Knife is a tool crafted by using the fabricator.

It's especially relevant for the survival mode of Subnautica as you will have to gain access to coral chunks in order to craft disinfected water.

In general, it can be used as a tool for harvesting or defense.

The Knife has a limited durability of about 100 strikes against an object.

By using the workbench the Knife can be upgraded to Heat Blade or Diamond Blade.

Trivia
Markings on the Knife indicate that it was made by "Alterra Arms Incorporated". Alterra is a corporation also known from the game Natural Selection 2, which was developed by Unknown Worlds Entertainment.
