title: Fatal chest injury caused by a vitrified (grindstone) wheel.
abstract: A 21-year-old 'handyman' was killed by a flying segment of a vitrified (grindstone) wheel while trying to sharpen a knife. The wheel disintegrated when driven by a vacuum cleaner motor capable of three times the recommended speed required to spin the wheel. The missile transected his great vessels and trachea.
