Abstract: A strengthened glass sheet or article having an edge profile that provides improved edge strength, particularly when the strengthened glass sheet is subjected to a four point bend test, and a method of making a glass sheet having such an edge. The edge is formed by cutting or other separation methods and then ground to a predetermined profile such as a pencil or bullet profile, a bull nose profile, or the like. In some embodiments, the edge is polished and/or etched following grinding to reduce flaw size.
