Okay, so do you remember how we talked about blacksmiths before? They are people who work with heavy tools and shapes metal into different things. Sometimes they even make weapons like swords!
So in this scene, we see a man who is a blacksmith working in his shop. He has a big fire burning in his forge and he puts a piece of metal into the fire to get it really hot. Once the metal is hot enough, he takes it out with big tongs and puts it on an anvil.
The blacksmith then uses a hammer to hit the metal over and over again, making it flat and shaping it into the desired form. This takes a lot of strength and the blacksmith has to be very careful not to hit his fingers!
As he continues to work, you might notice that the metal starts to cool down and become harder to shape. That's because it's not as hot as it was before, so the blacksmith has to put it back in the fire to heat it up again.
Finally, after a lot of hard work, the blacksmith finishes shaping the metal and he quenches it in water to make it even harder. And now he has created something new and useful!
