This mod will add a means to make it possible to return netherite tools and equipment to diamond once enhanced.

For starters, create a reinforced white paper material with paper and white dye

It can be used to create a blacksmithing mold to further convert it back into diamond.
It can be lowered to diamond by using a mold and equipment or tools on the forge stand, as well as reinforced white paper material.
For those who have already enhanced the enchantments and have lost their netherlight ingots and upgrade materials, there is a way to return the materials, but you will have to give up the enchantments that have already been applied.

Let's refine the reinforced white paper material in a blast furnace, and it will become black paper.
Upgrades and ingots will be returned if used in Craftingtable
