We just learned about the Fuller.
Another part of a blacksmith's forge is the slack tub.
This is the large tub of water that the blacksmith dips the metal in to cool it off.
If there is a part of the metal that the blacksmith does not want to get shaped, they can cool it down, and then only the hot part will be shaped.
For blade making, like swords or knives, the blacskmith uses oil instead of water.
