Heavier Horizons is a minecraft mod focused on implementing steel and other special tools.
Steel is a new material in between iron and diamonds that requires a bit more work to get. You make steel using a steel mill and input iron, coal, and coal dust. Steel armor has the same protection as diamond, at the cost of being significantly less durrable. Additionally, tools are efficent as iron tools, just having more durability. With steel, you can also craft a few more special items such as a steel magnet and a forge pickaxe to aid you in gameplay. Lastly, a global gamerule is implemented to enforce the "weight" of armor by slowing down players with more armor.
