Changes of the blade angle of the TPP cell scraper require slight pressure on the handle using the forefinger, thus pushing the handle downward towards the floor of the container. Slight rotation of the handle will then cause the blade to twist to the desired direction. The advantages of the cell scrapers: free rotating blade, total access to all corner, different blade widths, small raised knobs on the handle, lint-free blister packaging, user friendly TPP dispenser case.
