Cherry Burl is a domestic wood that is usually considered to be in the same class as mahogany for usage in the United States. It is described as wood for fine furniture. The stiff and strong wood is reported to work easily with both hand and machine tools. European and American black cherries are reported to be comparable in many aspects, but the latter is more plentiful. Both species are reported to be strong and tough and have been compared in strength properties to Yellow birch, and compares favorably with Teak. A burl is a tree growth in which the grain has grown in a deformed manner. It is commonly found in the form of a rounded outgrowth on a tree trunk or branch that is filled with small knots from dormant buds. A burl results from a tree undergoing some form of stress. Burls yield a very peculiar and highly figured wood, one prized for its beauty by many; its rarity also adds to its expense.
