What does the term serrated mean?

The term "serrated" refers to a structure that has a notched or toothed edge, resembling the teeth of a saw. This characteristic is commonly found in various biological contexts, such as in certain types of leaves or in the design of tools and utensils, where the serration enhances cutting ability. When a surface or edge is described as serrated, it implies that it has a series of sharp, pointed projections or indentations that create a jagged appearance, allowing for a more effective grip or cutting mechanism. This definition differentiates serrated edges from smooth, rounded, or flat surfaces, which do not possess this series of notches or teeth.
