US Patent 10537215 Ice scraper with offset chipping teeth

An ice scraper comprising a handle and a scraper head connected to the handle. The scraper head includes a proximal end, a distal end having a scraping edge, a scraping side, a chipping side, and at least three chipping teeth for chipping ice, hard snow, or frost from a curved surface. The chipping teeth extend outwardly from the chipping side. Each chipping tooth has a contact edge. At least one of the contact edges is offset forward or rearward of contact edges of two of the other chipping teeth so that at least one point of each contact edge can simultaneously contact the curved surface regardless of the scraper's position relative to the curved surface and regardless of a direction of the scraper.
