Finn grabbed the piece of red-hot piece of iron with the tongs and placed it onto the broad anvil.
George was the one with the hammer. He used all his strength to slam the hammer onto the piece of iron repeatedly.
The noise of metal clashing filled the entire garrison. It was so loud that a few soldiers heard it all the way from the garrison.
"Master Finn is really hard at work..."
The soldiers didn't disturb the workshop and continued with their business.
By hammering the iron over and over, George condensed it, removing any pockets or hidden holes inside the piece of metal. Additionally, this process also removed the impurities inside the iron, producing an even better steel than before.
This was a time-consuming and body-quenching task. George was able to do it non-stop because he had done it all his life. If it was an ordinary person, they would lose all their breath after a few swings.
