Flexible cutting blade for grass trimmers and rotary mowers

Abstract

A cutting blade for a rotating trimmer includes a loading section at a proximal end securable to the rotating trimmer, a flexible hinge section extending from the loading section, and a transition section extending from the flexible hinge section. A cutting section extends from the transition section to a distal end. The transition section and the cutting section are tapered at a taper angle toward the distal end. In some variations, a mass of the transition section is greater than a mass of the cutting section, and a center of gravity based on a mass of the cutting blade may be positioned closer to the loading section than the cutting section.
