Bench scrapers (also called pastry scrapers and dough cutters) are typically metal, though some are made of plastic. They are versatile tools that can be used to scrape together ingredients on a work surface, transfer ingredients from work surface to a bowl or pan, and cut dough without wrecking its structure, among other things. Some plastic pastry scrapers have one straight and one rounded edge. This allows you to use them on both the work surface and inside bowls for folding mixtures.
