He decided to start with the iron ingots since they were the most abundant. Fein heated up the forge and placed the iron ingots inside until they melted into a molten liquid. He then poured the liquid iron into a mold that he shaped earlier, which was a basic sword design from the book "All the basics of blacksmithing".
After waiting for the iron to cool, he retrieved the sword from the mold and examined it closely. It was rough and unrefined, but he was satisfied with his first attempt.
Next, Fein tried his hand at working with copper. He melted it down and poured it into a mold, this time shaped like a small dagger. He then used a hammer to shape and refine the dagger, as he learned from the book "Encyclopedia of blacksmithing techniques".
Fein was fascinated with the process of blacksmithing. He continued experimenting with different materials, such as silver and gold, creating various designs ranging from rings to decorative pieces.
