A manual edger is a tool used to create a clean, straight edge on your lawn. It is typically used along sidewalks, driveways and other hard surfaces. The blade on a manual edger is much like the blade on a lawn mower, but it is smaller and set at an angle. This allows you to create a precise edge without damaging your lawn.
There are many different types of manual edgers available on the market, but they all operate in basically the same way. To use one, simply place the blade against the surface you want to edge and push it forward. As you move the blade along, it will cut through any grass or weeds in its path and leave behind a clean, straight line.
