Are you making a card, pamphlet, booklet, or origami piece that requires clean folds and crisp creases? A bone folder is the answer. Used originally for folding letters and traditionally made of wood, bamboo, or genuine bone, this tool reached commercial popularity when, in 1889, J. C. Forman of Cleveland, Ohio, patented an aluminum version that was sturdy and cheap to manufacture. Today these tools, although still called bone folders, are made of a variety of plastics, woods, and metals (and there are still some made of genuine bone). To achieve a precise line and a knife-sharp crease, peruse our roundup below to find the best product for your needs.
