A handle extends substantially perpendicularly away from the upper surface of the first, substantially planar part and is configured with a spray device including a water supply and a sprayer, for spraying water onto an advance path of the edger. A control and vibration module is arranged on the upper surface of the substantially planar part and configured with a vibration element that vibrates the rectangular blade.
