Just a Wrench
Java mod listed for Minecraft 1.19–1.20. Downloads from the MC Java Mods app on Android.
I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.
Just adds a wrench. This is used to rotate all different kinds of blocks, such as stairs, slabs, logs, doors, trapdoors, repeaters, comparators, etc. If there is a block that seems like it could be rotated, but the wrench doesn't work on it, just add it to the "justawrench:wrenchables" tag in a datapack to try it!
For devs, there is an API for compatibility, see the wiki.
