Knotless Knot (Hair Rig): How to Tie It
The knotless knot is how every hair rig gets tied: it whips the hooklink down the hook shank while trapping a hair that presents the bait behind the hook rather than on it. It has caught more UK carp than every other rig combined, and the whipping angle helps the hook flip and take hold.

Step by step
How to tie the knotless knot (hair rig)
- 1
Tie the hair loop and mount the bait
Tie a small loop in the end of your hooklink and mount your boilie or pellet on it with a bait stop.
- 2
Set the hair length
Thread the other end of the hooklink through the back of the hook eye and set the hair length so the bait hangs roughly 1cm below the bend.
- 3
Whip down the shank
Holding the hair in place along the shank, whip the hooklink down the shank 6 to 8 times in neat touching turns.
- 4
Back through the eye
Pass the end back through the eye from the front.
- 5
Moisten and tighten
Moisten the whipping and pull everything tight with a slow, steady pull, then test the finished rig across your palm.
Two rules apply to every knot: wet it with saliva before pulling it tight, because dry friction weakens mono and fluorocarbon at the exact point you need strength, and tighten slowly, then test with a firm pull before you cast.
Get it right
Common mistakes to avoid
Letting the hair exit on the wrong side of the shank. The hair should leave the shank on the inside, in line with the hook point, so the bait sits behind the bend. A hair whipped to the outside makes the rig spin and present askew.
Threading the hooklink through the front of the eye. Going in through the back of the eye is what sets the aggressive line-to-shank angle that turns the hook; front-first undoes the geometry the knot exists to create.
Untidy, overlapping whipping turns. Gaps and cross-overs let the whipping slide under load, which changes the hair length mid-session without you knowing. Six to eight touching turns, every time.
Setting the hair length after whipping. Mount the bait and set the hair first; adjusting afterwards means unpicking the whole knot or fishing a hair you never chose.
Skipping the palm test. Drag the finished rig across your palm: it should flip and prick almost immediately. If it skids without catching, the hair exit or hair length is wrong, and no amount of casting will fix it.
How strong is it?
Because it whips down the shank rather than cinching at one point, it retains around 90% of line strength. Exact figures vary with line type, diameter and how well the knot is tied, so treat any percentage as a guide, not a guarantee.
When to use the knotless knot (hair rig)
Every hair rig you will ever tie, which in practice means most carp fishing and plenty of barbel and specimen work. Hair length is the adjustment that matters: shorter for small pellets, longer for big boilies.
Which lines does the knotless knot (hair rig) suit?
The knotless knot was designed around supple braided hooklinks, and that is still where it behaves best: soft braid whips down in neat touching turns and lets the bait move naturally. Coated braids work well too; many anglers strip the last couple of centimetres of coating so the hair hinges freely while the whipped section keeps its anti-tangle stiffness. Stiff fluorocarbon and mono can be whipped for combi-style rigs, but keeping stiff line in neat touching turns takes more care, and the finished whipping wants a blob of stripped coating or shrink tube to stop it sliding on very slick materials.
The bigger picture
How does it compare?
Where the knotless knot (hair rig) sits among the ten knots in the library, by the line types it suits, how much strength it keeps, how bulky the finished knot is, and how hard it is to tie.
| Knot | Best for | Strength retention | Bulk | Difficulty |
|---|---|---|---|---|
| Palomar Knot | Mono, fluorocarbon and braid | ~95% | Compact | Beginner |
| Grinner Knot (Uni Knot) | All line types | 90–95% | Moderate | Beginner |
| Improved Clinch Knot | Mono and fluorocarbon (not braid) | 90–95% | Slim | Beginner |
| Knotless Knot (Hair Rig)(this guide) | Braided and coated hooklinks | ~90% | Slim (spread along the shank) | Beginner |
| FG Knot | Braid to fluorocarbon or mono leader | 90–95% (of the braid) | Very slim | Advanced |
| Figure-of-Eight Loop | Mono and fluorocarbon hooklengths | 80–85% | Moderate | Beginner |
| Snell Knot | Mono and fluorocarbon (braid also snells well) | ~95% or better | Slim (spread along the shank) | Intermediate |
| Albright Knot | Two lines of clearly different diameters | 80–90% | Moderate | Intermediate |
| Surgeon's Knot | Two lines of similar diameter | ~90% (more in triple form) | Bulky | Beginner |
| Arbor Knot | All line types (braid needs backing or tape) | n/a — grip matters, not strength | n/a (buried on the spool) | Beginner |
Knotless Knot (Hair Rig): common questions
Tying hair rigs. It attaches the hooklink to the hook while leaving a hair extending past the bend to carry the bait, so the hook stays free to flip and take hold in the carp's bottom lip when the bait is sucked in. Almost every modern carp rig is built on it.
Set the hair so the bait hangs roughly 1cm below the bend while tying, then adjust for the bait: shorter for small pellets, longer for big boilies. On the finished rig the bait should sit just behind the bend; too long a hair lets a carp eject the bait without the hook turning.
Six to eight neat touching turns down the shank is the standard. Fewer can slip and lose the hooking angle; many more adds bulk without benefit. Keep the turns tight and touching, then pass the line back through the eye from the front.
Yes. Because it whips down the shank rather than cinching at a single point, it retains around 90% of line strength, and the load spreads along the whipping. It is effectively a snell knot with a hair coming out of the back.

Snell Knot
Spade-end hooks, where it is the only option, and any time you want the pull of the line aligned straight along the hook shank, which improves the hooking angle on bigger baits. Worth knowing on eyed hooks too.

Any time you need a loop: hooklength connections, feeder attachments and method rigs. Loop to loop is the quickest way to change hooklengths on the bank; just make sure the loops seat in a square handshake, not a strangling girth hitch, which costs you strength.
Read the guidePalomar Knot
Any time you tie a hook, swivel or snap link to mono, fluorocarbon or braid. Its only real weakness is practical rather than structural: the whole hook or lure has to pass through the loop, which gets awkward with big lures and treble hooks.
