Survival Knife (Subnautica)

The Survival 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 samples in order to craft disinfected water.

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

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

By using the workbench the Survival Knife can be upgraded to Thermoblade or Hardened Blade.
