Quick and dirty

As his hands worked furiously, Liam had already forgotten all about the unexpected visitor and focused on the flames beside him. 

He watched the stacks of iron ore melting and forming a sort of lump together and then melting altogether. He quickly removed this molten ore and poured it over a sand clay mold of a simple sword.

Giving the ore only a couple of seconds to take the shape of the mold, he quickly retrieved the raw unrefined sword and doused it in cold water.

He then once again placed the sword in the furnace and reheated the metal, after which he placed it on the anvil.

"Heh. I never thought that I would be doing this again." Liam chuckled. He almost lovingly looked at the piece of weapon and started hammering it.

Though it was not immediately obvious, this step was the most crucial in crafting a weapon. The more a weapon was hammered, the more powerful it became.
