Tool Belt Mod – Expand Your Hotbar with a Handy Belt
The Tool Belt is a cool mod that organizes your tools into a belt you can carry or wear with the Baubles mod. The basic belt gives you 2 extra slots, activated by holding down the R key.
By combining the belt with belt pouches on an anvil, you can extend it to have up to 9 slots.
This saves a lot of space in your inventory bar. To quickly switch tools, just hold down the R key and switch to the tool you need!
Moreover, it can hold flint & steel for portal creation or shears for sheep trimming.
It's also helpful for quickly changing between bows and swords when enemies are nearby.
