Usually done on plank grain wood, using open gouges, knives and chisels to carve away the non-image areas. Woods like birch, basswood, Japanese shina (in the Linden family), and some hard woods such as cherry and pear are the most common. Plywood is often used, especially for blocks requiring wider sizes. The resulting image is often bold and graphic, sometimes emphasizing the wood grain. It can be developed as a black-line cut or a white-line cut, or any combination. In the 15th Century Albrecht Durer mastered the woodcut, producing highly detailed and tonal images using primarily black-line cutting.
