The two parts are magnetically coupled and move in tandem when the handle part is pulled by the user. A cutting blade may be received within a blade holder which may be mounted to the scraping part by screws and coil springs. The blade holder may be mounted at an angle such as a forty-five degree angle to the surface being scraped. The scraping part may comprise hook and loop material as a scrubbing surface and may have a suction cup located on that surface contacting the substrate. The handle part may have a soft felt lining for contacting the substrate.
