Whipping knots are tied at the ends of ropes to prevent them from unraveling. They delay the natural tendency of a rope to fray and usually have more turns than binding knots. Tending to slip off the ends on prolonged use, you can make them permanent and neat by sewing them to the main rope. These knots are suitable for natural and synthetic stranded and braided lines, ropes and cables and can themselves be tied with twine or any rope. Applications include fly fishing, sailing, Boy Scouting, etc.
