Life-safety notice
TyingPoint's illustrations are for learning. For any life-safety use — climbing, rope access, rescue, or load-bearing rigging — seek qualified in-person instruction, and always inspect and test every knot before you trust your weight (or anyone else's) to it.
The handcuff knot's blunt name describes its historical use plainly: two adjustable loops formed from a single rope, joined at a shared woven center, sized to go around two wrists or ankles - a knot documented in older rigging and rescue references for exactly that restraining or securing purpose, alongside more benign uses tying together two similar bundles or objects.
Mechanically it is two identical loops, overlapped as though laying out a clove hitch, with each loop then passed through the other. The name oversells it badly, and published sources say so plainly: the knot has no inherent locking action, and it could never live up to its name. The loops run freely against each other, so pulling one tighter shrinks the other. That is not a sign of a badly tied knot - it is what the knot does. Set sizes only hold once the two loose ends are locked off, either with an overhand knot tying them together or with a half hitch from each end around the neck of the loop beside it.
Today its legitimate, actively used niche has shifted almost entirely to decorative rope work and knot-tying skill demonstration - it remains a genuinely interesting knot to learn for its dual-adjustable-loop mechanics, independent of its historical restraint-oriented name and use.
Where it retains a real, practical (non-decorative) application is tying together two roughly similar bundles or objects that each need their own loop - two coils of cable, for instance, or a matched pair of tool handles - a legitimate use that has nothing to do with the knot's original name or purpose but takes advantage of the same two-independent-loops mechanics.
Older rigging and rescue references documented it primarily as a historical curiosity even by the time those references were written, alongside more legitimate uses like temporarily hobbling an animal's legs for veterinary handling or securing a person's own belongings in transit - a spread of documented uses that reflects the same two-independent-loops mechanics being applied to whatever needed a matched pair of adjustable loops, only some of which involved restraining a person at all.
Knot-tying enthusiasts who collect and practice a wide range of traditional knots often include the handcuff knot specifically because its two-independent-loop-adjustment mechanic is genuinely different from most other knots on this site, which typically produce either one loop or two fixed, non-independently-adjustable loops - a real, distinct skill worth understanding on its own mechanical terms, independent of its loaded historical name.
How to tie the Handcuff Knot
- 1Form two identical loops in the rope, side by side.
- 2Overlap the two loops in the middle, the same way you would when laying out a clove hitch.
- 3Pass the left loop through the right loop, and the right loop through the left.
- 4Pull the two loops outward to draw the centre up. Set each loop to roughly the size you need.
- 5Lock the knot: tie an overhand knot with the two loose ends, or take a half hitch with each end around the neck of the loop beside it.
- 6Without that lock the loops slide - pulling one tighter will shrink the other. Do not skip step 5.
Strength & security
Two loops from a single rope, joined at a shared centre. On its own the knot has no locking action at all: the loops run freely against each other, so tightening one loosens the other. It only holds set sizes once the ends are locked off with overhand knots or half hitches, and even then it is a light-duty knot rather than a rated one.
Cautions: Not appropriate for restraining a person under any circumstance. It is also not a rescue knot: search and rescue teams avoid it because loops drawn tight around limbs can injure the person being moved, and applying traction to limbs this way is a last resort at best, for when nothing else is available. Its ordinary modern uses are knot-tying practice, decorative work, and tying together two similar bundles.

FAQ
What was the handcuff knot originally used for?
Documented historically as a way to put a loop around each of two wrists or ankles from a single rope, which is where the name comes from. It never worked well for that - published sources note it has no inherent locking action and could not live up to the name. It is also avoided in search and rescue, because loops drawn tight around limbs risk injuring the casualty.
Is the handcuff knot used for anything today besides its historical purpose?
Mostly decorative rope work and knot-tying skill practice, though its two-independent-loops mechanics also has legitimate practical use tying together two similar bundles or objects.
Why does this page cover a knot with such an uncomfortable historical name?
Because the knot itself - the two-independent-loop weave - is a genuinely useful piece of rope-work mechanics worth documenting honestly, the same way this site documents any other knot's real history, without pretending its old name or use never existed.
Why do knot enthusiasts still practice the handcuff knot?
Its two-independently-adjustable-loop mechanic is genuinely distinct from most other knots, which typically produce either a single loop or two fixed loops - a real, separate skill worth learning on its own mechanical merits, independent of its historical name.
Can the handcuff knot be tied with the loops facing different directions?
Yes - the two loops can be oriented however the intended use calls for, since the central weave doesn't force any particular relative orientation, which is part of why the knot adapted so readily to a range of documented historical uses beyond its literal namesake.
Is the handcuff knot difficult for a beginner to learn?
The weave itself is straightforward: two identical loops, overlapped like a clove hitch, each passed through the other. The step beginners miss is the lock - an overhand knot in the two loose ends, or a half hitch from each end round the neck of the loop beside it. Without it the loops simply slide against each other.
