The Matthew Walker knot is a decorative knot that is commonly used in various applications. It is primarily used to prevent the end of a rope from unravelling or to add a decorative touch to a rope or cord. The knot consists of multiple wraps around the standing part of the rope, creating a cylindrical shape.

Historically, the Matthew Walker knot has been used in maritime settings. Sailors would employ this knot to secure the frayed ends of ropes and prevent them from coming undone. It provided a durable and functional solution to keep the ropes intact in demanding conditions at sea.

However, in contemporary times, the Matthew Walker knot has become more popular for its decorative purposes. It is often used in crafts, jewellery making, and even as a knot in paracord bracelets. The intricate design of the knot makes it visually appealing and adds a touch of elegance to various items.

Overall, while the Matthew Walker knot has practical origins in the maritime world, its primary use today is for decorative purposes in a wide range of applications.
