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.

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

Usage

The Survival Knife's main function is to procure samples of certain flora and corals, such as Creepvine Samples and Coral Samples. Though it can be used as a weapon, its damage and range are limited, and there is no real benefit to killing fauna in the first place. The Survival Knife has a limited durability of about 100 strikes against an object. After it's durability goes to zero, the knife disappears.

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

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