A line blade (10) for a rotating trimmer includes a loading section (14) securable for rotation on a cutting plane with a head of the rotating trimmer. A living hinge (16) extends from the loading section (14). A transition section (18) extends from the living hinge (16) and has a first cross-sectional shape. The first cross-sectional shape is configured and oriented to reduce drag. A cutting segment (24) extending from the transition section (18) has a second cross-sectional shape that is different from the first cross-sectional shape of the transition section (18), where the second cross-sectional shape is configured and oriented for cutting vegetation. The multi-zone line blade improves cutting at lower speeds, thereby requiring less power.
