Survival Knots and Their Uses
Join. Bind. Hitch. Loop. Slide. Stop. Learn the job first—then choose the knot built to do it.
Read the rope
- Standing part
- The inactive length carrying or leading toward the load.
- Working end
- The free end used to form the knot.
- Bight
- A curved section that does not cross itself.
- Loop
- A turn where the rope crosses over itself.
A small set of well-practiced knots is more useful than dozens you only recognize. Each family solves a different problem: bends join ropes, binding knots compress objects, hitches attach rope to something, loops create a fixed eye, sliding knots move under no load, and stoppers keep a rope from passing through.
This visual guide is for general utility and practice. Climbing, rescue, fall protection, towing, and overhead loads require certified equipment, system-specific training, backups, and inspection by a qualified person. Never rely on a knot learned only from a webpage for life support.
Family 01
Bends
Join two rope ends. Match the bend to rope diameter, material, and expected load.
Sheet Bend
Joins ropes of unequal diameter. Form a bight in the thicker rope; the thinner working end passes through, around both legs, and under itself. Dress both tails on the same side.
Carrick Bend
A symmetrical bend for large, stiff, or heavy rope. It remains easier to untie after loading when tied with adequately long tails.
Hunter’s Bend
Compact interlocking bend for similar ropes. Dress it carefully so each working end passes through the opposite loop.
Reever Bend
A secure, symmetrical option that can work with slick line. Its similar-looking forms make careful dressing and inspection essential.
Zeppelin Bend
Strong, stable, and notably resistant to jamming. The “6 over 9” layout is a common memory aid before threading both tails through the center.
Family 02
Binding Knots
Wrap and compress a bundle or object. These are not substitutes for bends.
Reef Knot
Binds a package or reefed sail: right over left, then left over right. It can capsize or slip under unequal loading, so never use it to join critical ropes.
Miller’s Knot
A practical sack-closing knot that cinches around the neck of a bag and can be adjusted before final tightening.
Boa Knot
Built to compress long cylindrical bundles such as poles. The opposing turns grip the bundle as both ends are pulled.
Constrictor Knot
An exceptionally tight binding knot for temporary clamps and bundles. It may jam so firmly that cutting is the only removal method.
Family 03
Hitches
Attach a rope to a post, pole, log, or another rope.
Clove Hitch
Fast attachment around a post. Useful under steady, balanced tension but prone to slipping or jamming when the load changes; add backups when appropriate.
Half Hitch
A simple turn around an object followed by passing the end around itself. Best used as a supporting or finishing element, not alone.
Prusik Knot
A smaller loop wrapped around a larger rope to create a friction hitch that grips when loaded and slides when unloaded. Compatibility is critical.
Highwayman’s Hitch
A quick-release hitch that spills when its release end is pulled. Because accidental release is possible, keep it away from critical loads.
Rolling Hitch
Attaches to a pole or rope and resists pull mainly in one direction. Extra turns face the expected load.
Timber Hitch
Grips a log for dragging by wrapping the working end repeatedly around itself inside the turn. Maintain tension and never stand in the line of pull.
Family 04
Fixed Loops
Create a stable eye at the end or in the middle of a rope.
Overhand Loop
Fold a bight and tie an overhand knot with the doubled rope. Simple and compact, but it can jam badly after loading.
Bowline
Creates a fixed end loop that is often easy to untie. It can loosen when unloaded or ring-loaded; the tail, dressing, and backup matter.
Angler’s Loop
A compact fixed loop with good security in fine line. It can become difficult to untie after a heavy load.
Alpine Butterfly
Forms a strong loop in the middle of a rope and handles pull from several directions. Useful for isolating a damaged section in non-life-safety systems.
Family 05
Sliding Knots
Loops that move when unloaded and tighten when the standing part is pulled.
Slip Knot
A bight pulled through a simple loop creates a quick adjustable loop. It releases by pulling the free end and is not a secure life-safety knot.
Tarbuck Knot
An adjustable friction loop originally intended for early nylon line. Modern rope behavior varies, so test it only in noncritical systems.
Running Bowline
A bowline tied around its own standing part forms a sliding loop for retrieving or securing objects. Keep it away from people and animals.
Family 06
Stopper Knots
Enlarge the rope end so it cannot run through a hole, fitting, or another knot.
Double Overhand
Pass the working end through an overhand loop twice before dressing. Compact and secure, but often difficult to untie after loading.
Stevedore’s Knot
A bulky multi-turn stopper developed for cargo work. Its extra turn makes a wider stop than a figure-eight in many ropes.
Ashley’s Stopper
A large, symmetrical stopper suited to rope ends where a compact knot might pull through an opening.
Diamond Knot
A decorative and functional multi-strand stopper used on lanyards and handles. It takes careful dressing to keep every strand even.
Rope care
The Knot Is Only as Reliable as the Rope
Before each use, inspect the full length for glazing, cuts, flat spots, discoloration, chemical contamination, a stiff or soft core, and damaged stitching. Retire life-safety rope according to its manufacturer and qualified inspection—not a generic calendar.
Follow the manufacturer. Many utility ropes can be hand-washed in cool water with mild soap, then air-dried away from heat and direct sun.
Run the rope loosely through your hands and lay it in broad back-and-forth folds to remove twists and prepare it for deployment.
Use large, even loops without sharp bends. Secure the coil loosely and store it dry, clean, ventilated, and away from chemicals.
A very old technology
Ropework Built Ships, Shelter, and Trade
Humans have twisted fiber and tied knots since prehistory. Knots secured tools and shelters, supported fishing and transport, drove the rigging of sailing ships, and even recorded information through knotted-cord systems. The materials changed; the core problem did not: control a flexible line without permanently altering it.
Practice protocol
Learn by Function, Not by Count
Start with six: one bend, one binding knot, one hitch, one fixed loop, one friction or sliding knot, and one stopper. Tie each slowly, dress it neatly, load it in a safe test, inspect it from both sides, and untie it. Repeat until the structure—not just the hand motion—makes sense.
