Card scraper
Appearance
A thin piece of metal, usually rectangular, but often with curved sides as well, used to smooth the surface of wood. Bahco, Sandvik, Two Cherries are all examples of common band names of the scrapers. A file is used to joint (make flat) the surface in preparation of turning a burr with which the scraping is done.
Card scrapers can also be used to remove the finish from old furniture surfaces. Once the technique is master, large fluffy shavings with extremely unlikely tearout problems can be made. Witness David Marks on Woodworks from DIY network.
Turning the burr can be tricky, there are jigs available to assist in keeping a constant angle when jointing, and burnishing the edge to form the burr.
