# Show Wielded Item [`show_wielded_item`]
This Minetest mod displays the name of the wielded item above the hotbar and
statbars.
This mod is compatible with the HUD Bars [`hudbars`] mod.
Compability with other HUD-related mods is possible, but not guaranteed.
Version: 1.0.0
## Credits
Released by Wuzzy.
The original mod code was taken from the file “`item_names.lua`”
found in the Unified Inventory mod maintained by VanessaE. This code
has been later modified.
Original author: 4aiman
## License
This mod is licensed under GNU LGPLv2 or later
