Symbiotic Swiss Knife
by borealis
Symbiotic Swiss Knife is a Forge and NeoForge technology mod that combines several GregTech Modern tool types into one multitool that can be swapped on the fly.
What it does
Players slot other GregTech tool types into the multitool, and a single item then covers the work of several tools. Swapping between the stored tools can be done with a radial selector opened by the mouse, with shift and scroll for quick cycling, or through the Pick Block action, which picks the tool suited to the block the player is looking at. Each of these methods is set up so the tool order and selection can be customised.
The mod also includes a Single Block Mode. When it is toggled on, each attack action breaks only one block, which keeps players from clearing a whole cleanroom by accident when they only want to take out one machine. New tools are added by combining the multitool with other GregTech tool types at a crafting table, and the multitool supports the base GregTech tool types.
The mod is open source under the GNU Lesser General Public License v3.0 only, with public source code. It runs on the Forge and NeoForge loaders for 1.20.1, with the latest files dated 2026-06-10, and it is published as Client and server, so the server and every player need it.
