We just learned about the Punching.
Another thing blacksmiths do is called forge welding.
When a blacksmith has two pieces of metal that they want to stick together, like maybe a handle for a shovel, or a hilt for a sword, they get the two pieces of metal really hot, and then hammer them against each other.
The metal has to be so hot that it is almost melting into a liquid, and then the two metals get joined together.
In ancient times when people would make swords, they would take two types of metal and forge them together.
One type of metal would bend easily but never break, another type of metal would never bend, but could break.
By forge welding them together, they could make a sword that would never bend and never break.
