I am working on a remaster, I'll let you all know what the name is if it comes out!
This mod allows you to craft better tools with better ores.
How to make steel:
Put any iron tool / iron armor piece / iron ingot in the steel furnace and put some coal / charcoal in the fuel spot in the steel furnace.
Then just press "convert" and you will get your steel tool / armor piece / ingot.
If you don't know how to make a steel furnace then please see the screenshots.
