Which tool is generally used for edging lawns?

A string trimmer is the most suitable tool for edging lawns due to its design and functionality. This tool, also known as a weed eater or weed whacker, features a flexible monofilament line that spins at high speed, allowing it to cut grass and weeds in areas that are hard to reach with a traditional lawn mower or other larger equipment.

When edging, the goal is to create a clean separation between the lawn and adjacent surfaces like sidewalks, driveways, or flower beds, and the string trimmer excels in achieving that precise finish. Its lightweight and handheld nature make it easy to maneuver along edges, ensuring a professional and tidy appearance.

Other options like a leaf blower, lawn mower, and tiller do not fulfill the specific requirements for edging. A leaf blower is designed for clearing leaves and debris, a lawn mower is used for cutting grass at a consistent height, and a tiller is intended for breaking up and turning soil. None of these tools are equipped to create the clean, defined edges that a string trimmer can achieve effectively.
