The FG knot joins braided fishing line to a monofilament or fluorocarbon leader with a connection that stays small and strong
The FG knot (also called the Fujiwara knot) wraps the braided line around the leader in a series of tight, interlocking loops that create a knot smaller than most alternatives. The connection is reliable enough for saltwater and freshwater fishing where you need a leader — it holds under load and passes through rod guides without snagging. The trade-off is that it takes practice to tie consistently, and the wrapping motion is different from knots you may already know.
The knot works because the braid's multiple strands grip the leader as you wrap, and the tight coils distribute force across the connection rather than concentrating it at a single point. Once you understand the hand position and rhythm, you can tie it in under a minute.
Key Takeaways
- The FG knot creates a small, strong connection between braided line and monofilament or fluorocarbon leader that passes easily through guides.
- You wrap the braided line around the leader in a series of tight loops, alternating the direction of each wrap to lock the braid in place.
- The knot requires practice to tie smoothly, but once learned it becomes faster and more reliable than many other leader connections.
- Trim both tag ends close to the knot after tightening, and test the connection before fishing to make sure the wraps are even and secure.
What you need before you start
Gather braided line (the main line on your reel), monofilament or fluorocarbon leader (usually 20 to 40 pounds for most saltwater and freshwater work), and scissors or line clippers. The leader should be roughly the same diameter as the braid or slightly thicker — if it is much thinner, the wraps will slip.
Some anglers use a small piece of electrical tape or a rubber band to hold the leader steady while they work, especially when learning. This is optional but helpful if your hands are cold or wet. You do not need a knot-tying tool, though some people use one to help tighten the final wraps.
Step-by-step tying instructions
Step 1: Position the lines. Hold the leader in your left hand (if you are right-handed) between your thumb and index finger, with about 6 inches of tag end pointing away from you. Lay the braided line alongside the leader, with the braid's tag end also pointing away. The two lines should run parallel.
Step 2: Begin the first wrap. Using your right hand, take the braid's tag end and wrap it around the leader from left to right, making a loop that crosses over itself. The braid should encircle the leader and come back toward you. Pull the tag end snug but not tight — you are building the structure, not cinching it yet.
Step 3: Continue wrapping in alternating directions. Make a second wrap by bringing the braid's tag end around the leader from right to left, creating a loop that sits next to the first one. The wraps should stack neatly without overlapping. Repeat this alternating pattern — left to right, then right to left — for 8 to 12 wraps total. Each wrap should be snug enough that it does not slide, but loose enough that you can still adjust it.
Step 4: Tighten the wraps. Once all wraps are in place, hold the leader steady with one hand and gently pull the braid's tag end with the other, tightening each wrap in sequence from the first one toward the last. The wraps should cinch down evenly around the leader. This is where the knot's strength comes from — the pressure locks the braid's strands against the leader.
Step 5: Finish and trim. After the wraps are tight, tie a simple overhand knot with the braid's tag end around the leader to lock everything in place. Trim both tag ends close to the knot with scissors or clippers. The finished knot should be smooth and compact, with no loose strands.
Common mistakes and how to avoid them
The most frequent error is wrapping too loosely in the early stages, which causes the coils to slip when you tighten. Build each wrap with enough tension that it holds its position, even if you have to go back and adjust later. Loose wraps also make the final knot bulkier than it needs to be.
Another common problem is uneven wrapping — some coils sit on top of each other instead of stacking neatly beside each other. This happens when you do not maintain consistent hand position or when you pull the tag end at an angle instead of straight back. Keep your hand movements smooth and deliberate, and pull the tag end in line with the leader.
Some anglers make the knot too large by using too many wraps or wrapping too tightly from the start. Eight to ten wraps is usually enough; more than twelve can create bulk without adding strength. If the knot feels thick or stiff after tightening, you may have wrapped too many times or pulled too hard.
Testing the knot before you fish
After you tie the knot, hold the leader in one hand and the braided line in the other, and pull steadily with moderate force. The knot should not slip or move. If it does, the wraps were too loose or the leader is too thin for the braid. Retie and try again.
Some anglers also wet the knot with water or saliva before the final tightening — this reduces friction and helps the wraps seat more evenly. It is not required, but it can improve consistency, especially in cold weather when line is stiff.
When the FG knot is the right choice
Use the FG knot when you need a small, streamlined connection that will pass through your rod guides without catching. It is popular in saltwater fishing where leaders are common and guide clearance matters, and it works well in freshwater for pike, bass, and other species where a leader protects against sharp teeth or abrasion.
The knot is less ideal if you change leaders frequently — it takes longer to tie than a simple clinch knot, so if you are swapping leaders every few minutes, a faster knot may save time. For permanent or semi-permanent leader connections, the FG knot's small size and strength make it worth the extra effort.
Frequently Asked Questions
How many wraps do I need for the FG knot to hold?
Eight to ten wraps is the standard range for most line weights. Heavier braids (50 pounds and up) may benefit from ten to twelve wraps, while lighter braids (10 to 20 pounds) can hold with eight. The key is that each wrap is tight and evenly spaced, not the total number.
Can I use the FG knot with monofilament main line instead of braid?
The FG knot is designed for braided line because the braid's multiple strands grip the leader as you wrap. Monofilament is too slippery for this knot to work reliably. Use a different leader knot like the Albright or surgeon's knot for mono-to-mono connections.
What size leader should I use with the FG knot?
The leader should be roughly the same diameter as your braided line or slightly thicker. If the leader is much thinner, the wraps will slip under load. If it is much thicker, the wraps may not cinch down evenly. Most anglers use a leader that is one to three pounds heavier than the braid.
How long does it take to tie an FG knot?
After practice, most anglers can tie an FG knot in 30 to 60 seconds. The first few times you tie it may take two to three minutes as you learn the hand position and wrapping rhythm. Speed comes with repetition.
Is the FG knot better than the Albright knot?
Both knots work well for braided-to-leader connections. The FG knot is smaller and smoother, making it better for guide clearance. The Albright knot is faster to tie and easier to learn. Choose based on whether you prioritize speed or a compact connection.
