Well, the developers of MCBE did not include reverse crafting. Even repairing enchanted items does not favor the player. The creator of the Dismount Table modification found a unique solution to this issue.
How the Dismount Table Mod Works
However, you can’t just dismantle an item in Minecraft without preparation. First, you need to craft a special workbench from the mod.
Disassembling items (Dismount Table) can only be done using a specific tool (wrench), which also needs to be crafted in MCPE.
We open the special crafting table, placing the wrench in one slot and the item we wish to disassemble in another.
The resources obtained in MCPE are returned to the inventory. Enjoy your gameplay!
