How to Tie the Monkey Fist Knot
Usage
The Monkey Fist Knot is a woven ball tied into the end of a rope so the line has enough weight to throw across a gap. It began as a sailor's heaving-line knot, thrown ship-to-shore so a heavier mooring line could be hauled across behind it, and it still earns its keep in camping and everyday carry.
The ball is usually tied around a core — a marble, a wooden ball, a smooth stone — which gives it shape and heft. Most people tie theirs from a few feet of bushcraft paracord — it holds the wraps neatly and comes in enough colours for decorative versions.
Why Learn the Monkey Fist Knot?
The wrapping is the easy part; the tightening is the whole job. Because the three sets of turns cross each other, slack pulled out of one strand reappears in its neighbours. The sequence is far easier to follow in motion — the Knot IQ app animates the Monkey Fist Knot in 3D so you can pause and rotate it at every pass.
Common Uses
Sailing
- Weighting a heaving line when docking or mooring — the knot's original job. On commercial vessels it must be rope-only (see Safety).
Camping and Bushcraft
- Weighting a line to throw over a tree branch, though a purpose-made throw bag is better.
- Improvised counterweight or anchor around a large stone.
- Base knob for a rope swing, or a grip on a lanyard end.
Household and Everyday Carry
- Keychains, zipper pulls and knife fobs — the most common modern use.
- A large one in thick rope, no core, makes a dog tug toy.
- Glove-friendly toggle on firefighting bunker-gear pockets; ceiling-hung garage parking guide.

Notable Features
- Three interlocking axes: three sets of turns at right angles, each locking the other two.
- Carries a core: it can enclose a ball or stone, which no flat button knot can.
- Permanent once set: a tightened fist is a finished object, not a knot you untie.
How to Tie the Monkey Fist Knot
Step 1
Wrap three turns of the working end around three or four fingers of one hand. A U-shaped strip of wood or a small jig can stand in for fingers.
Step 2
Holding that first set in place, pass the working end through the middle and make three more turns around it at right angles — the horizontal pass over the vertical.
Step 3
Pass the working end through the middle again, changing direction a second time, and make a third set of three turns. This locks the first two and interlocks all three axes.
Step 4
Slip the fingers or jig out. Either insert a solid core — a stone, marble, or a wooden or golf ball — into the hollow centre, or tie an overhand knot in the working end and tuck it into the centre instead — a small fist works with no core at all.
Step 5
Begin tightening, working from the end nearest the buried core or stopper knot straight through to the other end. Do not tighten everything at once — take the slack out progressively and evenly across all six faces.
Step 6
Keep working until the ball is round and snug, with the same number of turns showing on every face. Expect this to take longer than the wrapping did.
Similar Knots
Heaving Line Knot vs. Monkey Fist Knot
- Advantage: The Heaving Line Knot is far faster, does not jam, and can be untied and resized.
- Disadvantage: Not as bulky or heavy, and it cannot enclose a core.
The Capuchin vs. Monkey Fist Knot
- Advantage: The Capuchin is quicker as a plain rope-end stopper or handle, and it can be removed.
- Disadvantage: Barrel-shaped rather than spherical, and cannot carry a ball.
Diamond Knot vs. Monkey Fist Knot
- Advantage: The lanyard knot is smaller, flatter and much faster to tie and dress for a fob.
- Disadvantage: Coreless and lighter — no use where you need mass.
Ashley Stopper Knot vs. Monkey Fist Knot
- Advantage: Ashley's stopper is quick, and forms a compact knob that will not pull through a fairlead.
- Disadvantage: No decorative presence, and none of the throwing weight.
Security Level
A Monkey Fist Knot carries no working load, so "security" here means whether it holds its shape — and a correctly tightened one does, indefinitely. The catch is that all of it is front-loaded into the tightening stage: a fist left loose or tightened unevenly will slacken and lose its shape in service.
Downsides
- Slow to tie: the wrapping is quick, the tightening is not, and there is no shortcut.
- Effectively permanent: a set fist is very hard to undo. Plan on cutting it off, so only tie it into cord you can afford to lose.
- Cord length is guesswork: no reliable formula has ever been published — cut generously and expect to waste some.
When NOT to Use the Monkey Fist Knot
- As a climbing anchor. Ashley records the old practice of jamming a fist into a rock crack as protection. It is not rated protection.
- As a weighted weapon. We do not recommend it, and in some jurisdictions a weighted fist meets the legal definition of a prohibited slungshot.
- Anywhere the line must come apart again. If you need that cord back, use a knot that unties.
History
The earliest documented appearance in print is credited by Ashley to E. N. Little's Log Book Notes, New York, 1888. Ashley gave the knot its own chapter in The Ashley Book of Knots (1944, Chapter 29, #2200–2211), covering its heaving-line, decorative and slungshot uses. That 19th-century weapon association prompted legal restrictions that survive in some statutes today.
FAQ
Is a monkey fist illegal to carry as a keychain?
Generally no, if it is unweighted — the restrictions target the weighted "slungshot" version. A hard core of steel, lead or stone can meet the legal definition of a restricted weapon in some places. Check your own jurisdiction.
Why is my monkey fist lopsided, or why will it not tighten?
Almost always one of two things: an uneven number of passes between the axes, or tightening strands out of order instead of working from one running end to the other.
What is the difference between a monkey fist and a Turk's head?
They look similar finished but are structurally different. A Turk's head is a single continuous line; a monkey fist is three separate interlocking circles, a structure described as a set of Borromean rings. Not interchangeable names for one knot.
How much cord do I need to start a monkey fist?
There is no published formula — the most-asked, least-answered question across the tutorials we sampled. Start long and note what worked for your cord and core size. A Knot Tying Kit is a cheap way to get the repetitions in without chewing through good rope.
Important Notes on Safety
On commercial vessels this is a regulatory matter, not a preference: a heaving-line monkey fist must be rope only, with no added weighting material. The UK Maritime and Coastguard Agency's Code of Safe Working Practices for Merchant Seamen states it at Section 25.3.2, quoted in the West of England P&I Club bulletin on inappropriate weighting material, which records linesmen cutting weighted fists off incoming lines and ports fining the vessels.
A heavily weighted fist thrown at or near a person can cause serious injury. Alert everyone in the area first, and only throw when the landing zone is clear.
