|This article is about the Thermoblade. You may be looking for the Survival Knife.|
In general, it can be used for harvesting or defense. The Thermoblade does less damage than the standard knife. However, 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.
- 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.
