A sharp blade sounds different — cleaner, lower, less argument with the grass — and that difference is the whole idea behind Spinblade. Come April the zoysia and Bermuda around Jonesboro wake up all at once, greening from the ball fields at Clayton County International Park out to every lawn on every side street, and the first real cut of the year sets the tone for the rest of it. Spinblade handles that cut and the ones after: mowing at the right height, edging the drives back to a line, trimming where the mower cannot reach, then clearing the clippings off the concrete. Jonesboro, Morrow, the neighborhoods ringing Lake Spivey, Rex and Stockbridge are all on the route. A lawn cut this way holds its shape until the next visit, and that is the point.
