A barrel knot is an adjustable knot that self-tightens when used to tie one rope, or monofilament nylon line, to another. This friction knot is often referred to by various names, including the blood knot, the [double fisherman’s knot](https://www.masterclass.com/articles/double-fishermans-knot-guide), or the double and triple overhand knot, though each knot has a different tying process. However, the barrel knot can be used as the foundation for a blood knot and other knots, like the double fisherman’s knot. 

The barrel knot can be used as a stopper knot on a rope or fly fishing line, a climbing knot for a belay device, or finishing knots or coil knots in macrame patterns and other decorative DIY projects. Though the barrel knot is useful in various situations, creating one can be challenging due to the degree of manual dexterity needed to tie it. 

There are many ways to use the barrel knot, including:

1. __Climbing or rappelling__: Climbers frequently use barrel knots as a stopper knot at the end of a rope to prevent it from untying or as the climbing knot on a belay device, which locks the end of the climbing rope and stops it from slipping through the device. Knotting multiple stopping knots on a length of rope can also create a climbing rope. 
2. __Decorative__: Barrel knots are essential knots for many decorative and creative projects. They are very effective macrame knots, also known as coil knots, but can also be used to create cord rosary or knotted rosary for lanyards or to knot bracelets and other jewelry.
3. __Fishing__: Barrel knots are frequently used as fishing knots to join monofilament lines of equal or similar size or diameter. The knot is a favorite for fly fishing or creating a fishing leader, which provides strength and security to the connection between the line and the hook and lure. It’s also a stronger, more complicated alternative to the uni knot.

There are several barrel knot variations. Among the most common are:

1. __Barrel knot on a bight__: Also known as an improved barrel knot, the barrel knot on a bight loops the working end of the rope—the end used to tie the knot—around a bight, which is a section of slack between the two ends of the rope. The loop can be created by using a connective weight, such as a fishing swivel.
2. __Barrel bead knot__: This variation is longer than the standard barrel and features three or more loops. It’s a decorative knot that can be used on longer sections of material.
3. __Sliding barrel knot__: A variation on the sliding knot, the sliding barrel knot is an adjustable knot that turns around the circumference of a loop, rather than a single strand of rope. It’s often used for bracelets or necklaces.

Here is a step-by-step knot tutorial on how to tie a barrel knot:

1. __Use your hand__. Take the working end of the rope and draw it out to approximately arm’s length. Place the rope in the palm of your hand. Lay the working end against the back of your hand, then wrap it around your hand, crossing it over the standing side of the rope—the side not involved in knot tying—to form an X.
2. __Make your loops__. Create two additional <a href='https://masterclass.com/articles/writing-101-what-is-parallelism' target='_blank' class='mc-text--link' data-mc-segment-trigger='true' data-mc-segment-event-type='Article Page Click' data-event-obj='{"textTag":"p","href":"https://masterclass.com/articles/writing-101-what-is-parallelism","linkCopy":"parallel","category":"automated-link"}' automatic='true'>parallel</a> strands by wrapping the working end around your hand a second time. You’ll now have three loops. Run the working end under the loops, starting near your thumbs.
3. __Tighten the knot__. Slide the three loops off your hand, making sure to keep them together. Dress the knot by pulling on both ends of the rope. Your knot should have about 18 inches of tail, which refers to the end of the rope extending from the knot. If you are using fishing wire, you can use the tail to create a second lure, known as a dropper.
