A '''card scraper''' or '''cabinet scraper''' is a [[woodworking]] shaping and [[Wood finishing|finishing]] tool. It is used to manually remove small amounts of material and excels in tricky [[wood grain|grain]] areas where [[Plane (tool)|hand plane]]s would cause tear out. Card scrapers are most suitable for working with [[hardwood]]s, and can be used instead of [[sandpaper]]. Scraping produces a cleaner surface than sanding; it does not clog the pores of the wood with dust, and does not leave a fuzz of torn fibers, as even the finest abrasives will do.

Card scrapers are available in a range of shapes and sizes, the most common being a rectangular shape approximately {{convert|60|x|180|mm|in|abbr=on|sigfig=1}} and with a thickness of {{convert|0.6|to|1.0|mm|in|abbr=on}}.<ref name=handverktoy>{{cite book |date = 1984 |title = Håndverktøy og håndmaskiner for trefagene |url = http://urn.nb.no/URN:NBN:no-nb_digibok_2013061706072 |___location = Oslo, Norway |publisher = Universitetsforlaget |page = 73f |isbn = 8200350991}}</ref> 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]] [[fingerboard]]s, small flexible rectangular scrapers are useful.

Similarly, a card scraper can be used to manufacture complex [[moulding (decorative)|moulding]]s by cutting the negative of the desired moulding into the steel, e.g. through filing or die cutting.

A [[scratch stock]] is a profiled card scraper that is held in an adjustable stop.

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.

The main drawback of a card scraper is that the usage is a difficult skill to master. It takes a bit of practice to turn the burr correctly and then the scraper must be presented to the work in the correct fashion. Also, due to the friction created in use, the card scraper can become hot enough to burn fingers.

Some woodworkers use the term "cabinet scraper" instead of "card scraper" for this tool. AWhile this is widely accepted a separate tool, also exists, called a cabinet scraper, which differs from the card scraper in havingthat it has a beveled edge like a plane. Calling a card scraper a cabinet scraper could cause confusion between these tools.

A variation of the card scraper is the scraper plane which consists of a hand plane body in which a card scraper is mounted. There are also various styles of holder which can be used for this purpose. These simplify the use of the card scraper and alleviate the problems associated with heat.

Burnishing jigs and other accessories are available to assist in turning the burr, which makes the card scraper more accessible to the novice.
