Snell Knot: How to Tie It
The snell knot whips the line around the hook shank instead of relying on the eye, aligning the pull of the line dead straight with the shank. That makes it one of the strongest connections in fishing, the only option for spade-end hooks, and a better hooking angle on bigger baits.

Step by step
How to tie the snell knot
- 1
Lay the line along the shank
Thread the line through the hook eye from the front and lay a long tag end along the shank. With a spade-end hook, simply lay the line along the shank.
- 2
Form a loop
Form a loop hanging below the hook.
- 3
Wrap the shank
Wrap the loop around the shank and the line 5 to 8 times, working up the shank in neat turns.
- 4
Cinch down
Hold the wraps in place and pull the standing line slowly until the whole knot cinches down tight against the shank.
- 5
Trim
Trim the tag end and check the line leaves the hook in line with the shank.
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 wraps cross or overlap as you cinch. The whipping must bed down as neat touching turns; hold the wraps under your thumb while you draw the standing line through, or the whole stack rides over itself and weakens.
Finishing with the line on the wrong side. On a spade-end hook the line must come off the inside of the shank, hard against the spade; off the outside, the spade's edge can cut the line and the hooking angle is ruined.
Too short a tag to work with. Snelling needs a long working end; skimp on it and the last wraps go loose while you struggle. Give yourself 20cm and trim the waste afterwards.
Letting the wraps slide over the eye or spade as you tighten. Cinch down slowly and keep the whipping positioned on the straight of the shank where it belongs.
Not checking alignment after cinching. Pull line and hook apart gently: the line should extend the line of the shank exactly. A snell that exits at an angle has the wraps seated wrong and gives up the knot's main advantage.
How strong is it?
Retains around 95% of line strength or better, because it whips around the shank rather than relying on the eye. 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 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.
Which lines does the snell knot suit?
Mono and fluorocarbon are the traditional snelling materials, and fine mono to small spade-end hooks is where most UK anglers meet the knot, usually via shop-bought hooks to nylon. Supple braid snells beautifully too; the carp world's knotless knot is the proof. The awkward customer is stiff, heavy fluorocarbon, which resists lying flat along the shank and produces gappy whipping unless you work slowly and keep constant tension. Whatever the line, the test is the same: the line must leave the hook in line with the shank on the inside, so the pull drives the point in rather than levering it out.
The bigger picture
How does it compare?
Where the snell knot 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) | 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(this guide) | 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 |
Snell Knot: common questions
Attaching a hook by whipping the line around the shank rather than knotting it at the eye. UK anglers mostly meet it through spade-end hooks to nylon, where there is no eye to tie to, but it also suits eyed hooks when you want the line pulling dead straight along the shank.
It can match or beat it. Because the snell spreads the load along whippings around the shank instead of cinching at one point, it retains around 95% of line strength or better. The palomar remains the more practical everyday knot; the snell wins where hooking angle or spade-end hooks demand it.
The knotless knot used for carp hair rigs is, in effect, a snell with a hair coming out of the back. Both whip the line down the shank, which is why both are strong and both encourage the hook to turn into the fish's mouth.
Five to eight neat turns up the shank is the standard range. Keep the wraps touching and tidy, hold them in place as you draw the standing line through, and cinch down slowly so the whipping beds evenly against the shank.

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.
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.
Read the guideGrinner Knot (Uni Knot)
Hooks, swivels and leads on any line type, especially when you need a dependable knot tied by feel in the dark or in heavy mono. Tie two grinners facing each other on overlapping lines and you have the double grinner, a sensible alternative to the FG knot for joining braid to a leader.
