Okay kiddo, imagine you have two different colors of playdough, and you squish them together over and over again until you have a ball with swirly colors. That's kind of like what people did to make damascus steel a long time ago.
But instead of playdough, they used different types of steel. They would take one type of steel and hammer it flat, then they would take another type of steel and hammer it flat on top of the first one. They would then repeat this process many times, sometimes using more than two types of steel.
After repeating this process many times, the different types of steel would be all mixed up and swirled together in a really cool-looking pattern, kind of like the playdough ball. This new mixed-up steel is called damascus steel.
But the cool thing is that damascus steel was also really strong and sharp. So, people started using it to make swords and knives because they were so good at cutting things.
It's still a really cool thing today, and people still use it to make knives and other things, even though we have much more modern ways of making steel now. So, damascus steel is a special type of strong and sharp steel that looks really cool because it has different kinds of steel all mixed together in swirly patterns.
