Lawn edgers are used for neatening turf and trimming along the edges of flower beds and lawns. Edgers come in non-powered, gas-powered edger and electric models. With manual edgers you have to bend down and it can be hard on your back. Walking edgers are designed so that your simply walk along your lawn's border and place your foot on the blade to do the edging. While gas-powered edgers tend to be a little cheaper then electric edgers, the smell of the exhaust can be nauseating. On the other hand, the long cord on an electric-powered edger can be awkward. Handheld and non-powered edgers cost from $15 to $40 online; gas-powered and electric edgers range from $85 to $250. Professional electric edgers start at $600 online.
