You feel it first through the braid - that sharp tick as your lure gets bumped, then the weight comes on. The fish turns, you lift, and everything loads up… until it doesn’t. If your leader knot is bulky, poorly seated, or finished in a hurry, that’s when it pings at the worst possible moment - usually right as the leader hits the top guide.

That’s exactly why the FG knot has become the go-to braid-to-leader connection for serious anglers. It’s slim, strong, and it flies through runners far better than most alternatives. The trade-off is simple: it’s not the fastest knot to learn, and it demands tension. Get those two things right and it’s one of the most reliable connections you can fish.

Why anglers bother learning the FG knot

The FG isn’t a “knot” in the traditional sense where two lines tie around each other. It’s a series of braid wraps that bite into the leader like a Chinese finger trap. Under load, the braid constricts onto the leader rather than relying on a single sharp bend that can weaken mono or fluorocarbon.

That matters in SA fishing where plenty of common setups involve long leaders. Think squid jigs and egi rods with light braid, surf spinning with abrasion resistance in the wash, and inshore snapper or kingfish work where you want the leader to take the punishment near reef and jetty pylons. A slim, well-finished FG helps you cast further and reduces that annoying clunk through the guides.

It also shines when you’re stepping up leader size. Albright-style knots can start getting chunky when you join PE braid to heavier leader. A neat FG stays surprisingly compact.

Before you start: line choices and a quick reality check

The FG works with braid to mono or braid to fluorocarbon. Most anglers use it for fluorocarbon leaders because fluoro is stiffer and abrasion-resistant, but it’s also a bit more unforgiving if you rush the seating step.

As a rough guide, it’s easiest to learn on medium gear - say 10-20 lb braid to 15-30 lb leader. Ultra-light braid can be fiddly because it’s harder to maintain tension and the wraps can stack untidily. Heavy leader (40-80 lb) is fine, but you must cinch it properly or it can creep.

If you’re fishing very light leaders (for example bream and whiting with 4-8 lb), an FG is still excellent, but be honest about your conditions. If you’re retying constantly in wind and low light, a quicker knot may suit better. For most lure and bait applications where you want the smoothest join possible, the FG is worth the effort.

How to tie FG knot step-by-step (the shop-floor method)

There are plenty of variations, but the version below is consistent, strong, and easy to repeat once it clicks. The key is constant tension in the leader while you do the braid wraps.

Step 1: Set up tension

Cut a leader length you actually want to fish, not a short practice stub. Hold the leader under tension - a simple way is to wrap it once around a finger or pinch it against the rod butt. Some anglers put the leader in their teeth. It works, but if you slip, you’ll know about it.

Keep the braid coming off the spool with light tension too. You’re trying to keep both lines controlled so the wraps lay tight and neat.

Step 2: Start the braid wraps

Lay the braid over the leader at about a 90-degree angle and start alternating wraps.

Think of it as: one wrap over and around the leader, then bring the braid back and wrap from the opposite side. The braid should form a neat criss-cross pattern along the leader. Each wrap must be snug as you go. Loose wraps are the number one reason an FG slips.

Step 3: Build enough wraps for your leader

For most day-to-day setups, you’re aiming for roughly 16 to 24 alternating wraps. Thicker, harder leader usually benefits from a few more wraps. If you’re tying braid to very smooth fluorocarbon, don’t be shy about adding wraps - it helps the braid bite.

What you’re looking for is a tidy, even “barrel” of braid on the leader. If the wraps are bunched, crossed irregularly, or gappy, reset it. It’s faster to redo than to lose a fish.

Step 4: Lock the wraps with half hitches

Once you’re happy with the wrap section, keep tension on everything and tie two half hitches with the braid around both the braid and the leader (together). Pull each one tight. This stops the main wrap section from unravelling while you finish.

Step 5: Seat the knot properly (this is where strength comes from)

Now you need to “set” the FG so the braid digs in. Wrap the braid around your gloved hand or use a line puller if you’ve got one, and pull on the main braid while holding the leader. Then pull on the leader. Alternate and really load it up.

You should feel it tighten and compact. If you skip this, the knot might look fine but it can creep under the first big hit.

Step 6: Trim the leader tag close

Trim the leader tag end as close as you can without nicking the braid. A set of sharp scissors or snips makes a big difference here, especially with fluorocarbon. If you leave a long tag, it will tick through your guides and can catch weed.

Some anglers prefer a tiny tag as a safety margin on slippery leaders. That’s fine, but keep it minimal.

Step 7: Finish with braid-only half hitches

Now tie a series of half hitches with the braid around the braid only (not including the leader). This creates a clean finishing section and helps stop the knot from loosening over time.

Aim for about 4 to 8 half hitches, pulled snug each time. If you’re fishing hard or using heavier drag, do a few extra. It’s cheap insurance.

Step 8: Add a final locking finish

Finish with a simple locked hitch or a small Rizutto-style finish if you know it. The goal is to stop the final half hitch chain from walking.

Trim the braid tag close.

Common FG problems (and the fixes that actually work)

Most FG failures aren’t mysterious. They’re almost always tension, seating, or finish.

If the knot slips and the wraps slide off the leader, your wraps were loose or you didn’t seat it hard enough before trimming. Next time, keep leader tension constant during the wrap phase, then properly load the knot before you cut the leader tag.

If the knot “clicks” through the guides, it’s usually a long leader tag, a messy wrap stack, or too many bulky half hitches around both lines at the start. Keep the wrap barrel neat, trim the leader close, and move to braid-only half hitches after the initial lock.

If your leader breaks at the knot, you may be cinching in a way that burns or nicks the leader, especially with fluorocarbon. Pull smoothly, wet the knot lightly before the final hard seating, and don’t use damaged leader. Also check you’re not creating a sharp bend at the leader tag by trimming at a bad angle.

If it takes you five minutes every time, you’re not alone. Speed comes from consistency. Tie the same version, the same way, until your hands do it without you thinking.

When the FG is the right call - and when it isn’t

The FG is a top choice when you want a long leader for abrasion resistance and you need the knot to travel through the guides. That’s most lure work, a lot of squid fishing, and plenty of inshore bait fishing where you’re casting rather than dropping straight down.

If you’re fishing bait off a jetty with a short leader and you never wind the knot through the guides, you might not need an FG. A simpler knot can be perfectly adequate and easier to tie with cold hands at night.

If you’re game fishing with very heavy leaders and wind-ons, your connection system may be different again. The FG still has a place in some setups, but it depends on your leader material, your drag, and how your guides and rollers handle knots under load.

A few practical gear notes that make FGs easier

Sharp cutters are underrated. Fluorocarbon is hard on cheap scissors, and a ragged leader tag makes even a good FG feel messy.

A small line puller or a pair of gloves helps you seat the knot properly without slicing your fingers on fine braid. If you’re tying on the beach or in a windy carpark, anything that helps you maintain tension will improve your results.

If you need braid, leader, cutters, or rigging tools in one hit, it’s the sort of restock you can knock over in a single order from Reel ’N’ Deal Tackle rather than running around piecing it together.

FAQs

How many wraps should an FG knot have?

Most anglers land in the 16-24 alternating wrap range. Thicker or smoother leader usually likes more wraps. What matters is tight, even wraps and a hard seat.

Should I wet an FG knot before tightening?

A light wetting before the final hard seating is a good habit, especially with fluorocarbon, because it reduces heat and friction. Don’t soak it to the point you lose grip and tension.

Can I tie an FG knot at night?

Yes, but it’s harder to keep wraps neat and tension consistent. If you’re learning, practise in daylight until you can tie it by feel. A headlamp and a steady surface (even the tailgate) make a big difference.

If you want the FG to earn its spot on your rig, don’t chase speed first - chase repeatability. Tie it the same way, pull it down properly, and you’ll spend less time retying and more time doing what you drove out for: putting pressure on fish when it matters.
