What is the Metal Blade, and what is it used for?
Become the envy of every survivor by crafting your own shiny new metal knife in Green Hell. The Metal Blade is the next best thing to a proper survival knife and is the most durable blade in the game and one of the most powerful.
This guide will walk you through how to craft a Metal Blade in Green Hell and offer some tips on how it can best be used as a weapon.
How to craft a Metal Blade in Green Hell


Before crafting any metal tool, the player will need a functioning Mud Forge, some melted iron, and some empty molds. This particular recipe will require you to cast a Metal Blade.
Once you’ve forged the metal portion of the tool, you can assemble it by combining the following materials:
- 1 Rope
- 1 Metal Blade Cast
Rope can be collected by gathering Liana vines off of large trees. Metal Blade Casts can only be created by Forging and harvesting Metal Blade Molds.
Once you’ve collected the proper materials, craft the Metal Blade by:
- Opening the radial menu (by holding the C key)
- Select crafting from the options
- Drag the rope and Metal Blade Cast to the crafting rock from the backpack or environment
- Press the craft button above the crafting rock
Note: The crafting menu can also be opened from the inventory sidebar or by holding the alt-select button (default RMB
) over one of the ingredients and press craft.
How to equip the Metal Blade

The Metal Blade can be found in the tools tab of the inventory and occupies one of the four standard tool slots (numbered 1-4) or the additional knife slot at the far right. It can be equipped at any time by pressing the number key corresponding to the slot this tool occupies.
Note that items in the knife slot cannot be equipped but may still be used for certain actions requiring a blade, such as harvesting animals.
Tips and tricks for using the Metal Blade



The Metal Blade is the sturdiest member of its category and is the strongest item capable of being stored in the knife slot. The only blade capable of rivaling it in terms of damage is the Rusty Machete.
It is useful for any activities that normally require a knife, such as butchering animals, harvesting herbs, opening coconuts, or even combat, if necessary.
This blade can be used to chop down trees and split wood if necessary. However, it isn’t very good at these tasks nor a good substitute for a proper axe.
If you have to use a short blade in combat, you can’t do much better than this one. It is best to use caution when fighting with a Metal Blade in combat, as its short reach requires the wielder to get dangerously close to enemies.
When using this tool in combat, focus on dodging to the side of attackers to avoid damage while allowing you to close the distance between you and your opponent. Throwing the blade is also a valid strategy, but its high material requirements make it a costly tool to lose if you miss your target or they run away with it stuck in them.
We recommend waiting to craft metal tools until your crafting skill is at least above 30. While metal weapons and tools naturally degrade much slower than other items, crafting a low-durability metal tool still feels like a waste of precious iron.
Final thoughts on the Metal Blade
At last, a proper knife. While this tool is a simple construction overall, Creepy Jar realized the incredible value of having a Metal Blade of any kind when out in the wild. Making one for yourself is a sign you truly know how to make your own way in the jungle.
