Types of Card Scrapers
Card scrapers are available in a range of shapes and sizes, the most common being a rectangular shape of around postcard size. Another common configuration is the gooseneck scraper, which has a shape resembling a french curve and is useful for scraping curved surfaces. For scraping convex shapes such as violin fingerboards, small flexible rectangular scrapers are useful.
Scrapers are normally made from high carbon steel. There are many manufacturers who provide scrapers in a wide variety of styles. Many woodworkers prefer to make their own card scrapers by cutting them from old hand saw blades.
Card scrapers are sometimes used in working with ceramics, where they may substitute for the more traditional wooden rib. The scraper is also useful for trimming damp or dry clay. Such a scraper, the nearest one to the camera, is shown in the image at right.

Famous quotes containing the words types of, types and/or card:
“Our children evaluate themselves based on the opinions we have of them. When we use harsh words, biting comments, and a sarcastic tone of voice, we plant the seeds of self-doubt in their developing minds.... Children who receive a steady diet of these types of messages end up feeling powerless, inadequate, and unimportant. They start to believe that they are bad, and that they can never do enough.”
—Stephanie Martson (20th century)
“The bourgeoisie loves so-called “positive” types and novels with happy endings since they lull one into thinking that it is fine to simultaneously acquire capital and maintain one’s innocence, to be a beast and still be happy.”
—Anton Pavlovich Chekhov (1860–1904)
“There is undoubtedly something religious about it: everyone believes that they are special, that they are chosen, that they have a special relation with fate. Here is the test: you turn over card after card to see in which way that is true. If you can defy the odds, you may be saved. And when you are cleaned out, the last penny gone, you are enlightened at last, free perhaps, exhilarated like an ascetic by the falling away of the material world.”
—Andrei Codrescu (b. 1947)
