This invention is a sharpening device for lawn edger blades. The device is specifically designed for attachment to the machine and in use for when the machine is in operation. The reason for this is to keep the cutting edge of the blade continually sharp. The attachment is positioned near the cutting edge and sharpens the blade as it rotates. A manual switch or lever activates the sharpener as the user desires. The sharpener includes a caliper with an abrasive surface to squeeze against the rotating blade while the edger is in operation.
