Abstract
Abstract A hand scraper for griddles and the like has a support (11) for a blade (12) removably secured by a screw (13) projecting forwardly and downwardly from a handgrip (10), and a guard (14) which is conveniently formed of stainless steel rod, is spaced from the underside of the handgrip to afford protection of the fingers and to serve as a stable base for the scraper when not in use. An upwardly extending shield (33) is provided adjacent the blade support (11), to protect the hand from hot fatty debris pushed up over the blade (12).
