is the longest fiber obtained from the flax straw after the scutching process. The scutching process separates the impurities from the raw material, such as the seeds from raw cotton or the straw and woody stem from flax fibers. Scutching can be done by hand or by a machine known as a scutcher. Hand scutching of flax is done with a wooden scutching knife and a small iron scraper. The end products of scutching flax are the long flax fibers, short coarser fibers called tow and waste woody matter called shive.
