A "weed eater," also known as a string trimmer or line trimmer, is a gardening tool used to cut grass and weeds in areas that are difficult to reach with a lawn mower. It typically consists of a long shaft with a rotating head that uses a flexible nylon line to trim vegetation. This tool is especially useful for edging along sidewalks, fences, and flower beds. Weed eaters can be powered by electricity, batteries, or gasoline, making them versatile for different gardening needs. They come in various sizes and designs, allowing users to choose one that fits their specific tasks. Proper safety gear, such as goggles and gloves, is recommended when using a weed eater.
