Okay kiddo, back in the Bronze Age, which was a really long time ago before people had things like electricity and cars, they used to make swords out of a type of metal called bronze. It was made by melting tin and copper together, and then putting that melted metal into a mold to make a sword shape.
The sword was sharp, but not as sharp as the swords we have today because they didn't have the technology to make them that way. They also didn't have machines to make the swords, so they had to do it all by hand.
Bronze age swords were really important for people back then because they used them for protection and hunting. They were also a symbol of power and strength. People who were able to afford to have a sword were seen as important and powerful in their community.
Today we don't use bronze swords anymore because we have better technology and materials that make better and safer weapons. But back then, bronze swords were a really big deal and helped shape the course of history.
