Abstract: A scraper device comprises a carrier presenting a working face and including two slot formations disposed at different angles to the plane of the working face. An elongate scraper blade, such as a conventional hack saw blade, is releasably mountable in either one of the slot formations in either of two operative positions. In each of the operative positions the working edge of the scraper blade protrudes transversely from the working face and portion of the scraper blade can project from the carrier on at least one side of the carrier to permit a projecting portion of the scraper blade to be severed from a portion of the blade which is operatively mounted on the carrier.
