FG Knot
Quick Answer
The FG Knot joins braided line to a fluorocarbon or monofilament leader by weaving the braid around the leader in alternating half-hitches, then locking with half-hitches. It retains about 98% line strength and creates the slimmest, strongest braid-to-leader connection.
The FG Knot stands in a class of its own among braid-to-leader connections. Unlike traditional knots that wrap around a loop, the FG Knot weaves the braided line back and forth over the leader in a series of alternating half-hitches, creating a finger-trap grip that actually tightens under load. The result is an incredibly slim, strong connection that slides through rod guides as if it isn’t there. It consistently tests near 100% of the braided line’s rated strength, which is why it has become the gold standard for serious offshore, inshore, and big-game anglers worldwide.
How to Tie the FG Knot
- Tension the braided line between your hands or by holding the rod and looping the braid over a finger. The braid must be taut throughout tying.
- Lay the leader behind the tensioned braid at roughly a 45-degree angle.
- Weave the leader over and under the braid by alternating sides — push the leader over the braid from the left, then from the right, creating an X-pattern. Repeat for 15 to 20 alternating weaves.
- Lock the weave with a half-hitch using the braid around the leader above the woven section. Pull it tight.
- Add 3 to 4 more half-hitches, alternating which side you throw them on, to secure the woven section.
- Trim the leader tag end flush with the last locking hitch.
- Continue adding 3 to 4 finishing half-hitches over the leader stub only, building a small thread ramp that prevents the connection from catching on guides.
- Trim the braid tag end close and carefully melt the braid stub with a lighter to create a tiny mushroom tip that cannot pull through.
When to Use This Knot
The FG Knot is the best choice whenever a slim, maximum-strength braid-to-leader connection matters. If your fishing demands long casts, heavy drag settings, or the ability to clear guides under pressure, this is the knot to learn.
- Offshore trolling and jigging where the knot must withstand extreme loads from powerful fish
- Inshore and flats fishing where long casts require a knot that flies through guides without catching
- Bass tournament fishing where casting distance and sensitivity are competitive advantages
- Any application pairing braided mainline with fluorocarbon or monofilament leaders up to 200-pound test
Pro Tips
- Maintain firm, consistent tension on the braid throughout the entire tying process — slack braid is the number-one reason the FG Knot fails.
- Each weave should be snugged individually by pulling the leader tag; loose weaves pile up and create a bulky, weak knot.
- Practice with brightly colored braid and heavy leader at home until you can tie it confidently; this is not a knot to learn for the first time on a rocking boat.
- A finished FG Knot should feel completely smooth when you run it through your fingers — any bump or irregularity means wraps are uneven and the knot should be retied.
Pros and Cons
Pros:
- Strongest braid-to-leader knot available, regularly testing above 95% line strength
- Extremely slim profile that passes through guides with virtually zero resistance
- Does not require a loop in the leader, keeping the overall connection as thin as possible
- Tightens under pressure due to the finger-trap weave design — it gets stronger, not weaker
Cons:
- Steep learning curve that requires significant practice before it can be tied reliably
- Must be tied under constant braid tension, which is difficult in wind, waves, or darkness
- Time-consuming compared to simpler alternatives — even experienced tiers need a few minutes
- If any step is done poorly, the entire knot can unravel, making consistency critical
