Imagine a knife that isn't just straight; it has a wavy, tooth-like edge. That's serrated! It means having a notched or tooth-like edge, kind of like a saw. Think of it as the opposite of a smooth blade. Serrated edges are great for cutting things that are tough or fibrous, like bread or tomatoes. Unlike a perfectly smooth blade, serrated edges create small points of pressure. This allows it to slice through surfaces more easily than a regular straight edge. Basically, it's like having lots of tiny knives working together.
