serration
This term describes a specific physical geometry characterized by a saw-like edge. It is most frequently encountered in technical, botanical, or culinary contexts. When referring to a single notch, it describes a physical feature; when referring to the quality of the edge, it describes a structural property.
In botany, the term is used with high precision to describe leaf margins, where it distinguishes a jagged edge from a smooth (entire) or lobed one. In tool design, it refers to the functional teeth of a blade intended to grip or tear through tough materials.
