<human>:  What is the difference between a serrated and non-serrated knife?
<bot>: The main difference between a serrated and non-serrated knife is the type of edge. A non-serrated knife has a straight, smooth edge, whereas a serrated knife has a blade with a jagged edge. The jagged edge of a serrated knife can provide more control for slicing tough or delicate food items. The downside of a serrated knife is that it can be tricky to sharpen and can damage delicate materials, like bread or tomatoes.
