Weapons were removed from standard survival blueprints following the massacre on Obraxis Prime. As an essential survival tool for 2.5 million years, the knife remains the only exception. Sorry about that.

― PDA, Dialogue

The Survival Knife is a basic tool crafted by using the Fabricator.

Usage

Its main function is to procure samples of certain flora and to ward off aggressive fauna. 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. The Survival Knife has a limited durability of about 100 strikes against an object.

By using the Modification Station, the Survival Knife can be upgraded to Thermoblade or Hardened Blade.

If a Bleeder latches onto the player's arm, the player can use the Survival Knife to stab the Bleeder.
