Thermoblade (Subnautica)

The Thermoblade is a tool and an upgrade to the Survival Knife. It is crafted by using the Modification Station.

In general, it can be used for harvesting or defense. Its primary function is that it cooks any edible fish in one swipe.

If a Bleeder latches onto the player's arm, the player can use the Thermoblade to hit the Bleeder. The Thermoblade is unique in this situation as it can cause the Bleeder to detach in a single hit, whereas other tools do not have this ability.

Trivia

 * Markings on the Thermoblade indicate that it was made by "Alterra Arms Incorporated".
 * The boiling water effect is tied to the Thermoblade itself rather than the environment it is in. As a result, even when the player is in a base or above the surface, the blade will still appear to be surrounded by boiling water.
 * The Thermoblade once had durability, but it was removed due to durability being deemed useless.
 * When the Thermoblade did have durability, it had the lowest durability out of all the knives.
