A number of years ago we met a nearly blind inventor named Don Moore, who had patented a pair of curved rake heads. I was personally quite skeptical of his claims that the curvature made the rakes more useful than conventional rakes. I was astounded to try them out and discover that they both had remarkable properties not shared by straight rakes. After licensing the designs from Mr. Moore, we didn't have much luck persuading the public to try the full sized versions of these rakes. However, everyone seems to love the Mini version of the GroundHog rake. We find that it's perfect for raised bed gardening and kids.
