A shaving horse is designed for shaping long narrow pieces of wood. You sit on one end and pull a drawknife, spoke shave, or other tool toward you. As you pull with your hands, you push with your foot against one end of a treadle. This treadle in turn, holds the work in place. Hence, the harder you try to move the work, the harder you hold it in place.
