About this Mod

title

This mod adds a Symbiotic Swiss Knife to GregTech modern.

This tool lets you slot any other kind of GT Tool into a singular tool for extreme QOL swappability! It's got all your tools in one.

You can also read the description of the item in game for more information.


Switching

You can easily swap between tools through three different methods. 

The multitool selector UI

You can use your mouse to freely select in a radial wheel the multitool of your choosing!

Selector wheel

Scroll Wheel

Holding the multitool while shifting and scrolling will quickly swap between each item in order! Use this for quick swapping.

And the most powerful! The Auto-Select!

By pressing Pick Block, the multitool will automatically select the best tool for the purpose for the block the player is looking at.

This lets you rapidly swap between tools easily, and this is entirely customisable!

Auto Select Rules


Single Block Mode

Tired of breaking your clean rooms due to your wrenches being too fast? We've got you covered with the Single Block Mode.

Single block mode toggle

Once toggled on, you'll only be able to break one block per attack action! This means no more obliterating your entire cleanroom when you just want to break one machine.


Adding Tools

You can easily slot new tools by combining the multitool with any other GT Tool type in a crafting table. The multitool supports all base GT tool types:
