Handcuff Knot
decorative knot
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's built from two interlocking loops woven together at their overlap, adjusted afterward by feeding slack through that central weave to set each loop's size somewhat independently before the whole thing is snugged. Getting both loops to hold their set sizes without one collapsing or expanding when the other is tightened takes some practice.
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
Form two interlocking loops side by side, overlapping in the middle like a figure-eight.
Strength & security
Produces two adjustable loops from a single length of rope, historically used to bind two wrists (or ankles) with independently sized loops joined at a shared center - the origin of its blunt descriptive name.
Cautions: This is not rated or appropriate for restraining a person against their will under any circumstance; its legitimate modern uses are decorative rope work, tying two similar-sized bundles together, or as a knot-tying skill exercise.
Alternatives
- Bowline on a Bight
A more secure, better-documented double-loop knot for genuine load-bearing use - the handcuff knot's real niche today is decorative or improvised binding rather than serious load-bearing work.
FAQ
What was the handcuff knot originally used for?
Documented historically as a way to bind two wrists or ankles with independently sized loops from a single rope - hence its descriptive name.
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?
Somewhat - the interlocking weave at the center takes a bit more spatial visualization than a simple single-loop knot, but most people who've already learned a basic bowline or figure-eight loop can pick up the handcuff knot's mechanics within a short practice session.
