Allows you to recycle your damaged tools and armor in the blast furnace.
This mod allows you do melt down tools and armor back to materials in the blast funace.
The amount of materials you get back depends on durability.
All these items can be recycled in the blast furnace by default.
A diamond nugget is added so that you can melt down damaged diamond equipment.
