This is where tools specially designed to simplify the making of this demanding knot come into play. They save time, improve knot consistency and, above all, guarantee optimum strength.
What are these tools for?
Maintain constant tension on the braid: the FG knot relies on tight wraps of fluorocarbon around a well-tensioned braid. A tool like Daichiseiko's Knot Assist 2.0 allows you to maintain this tension effortlessly, while leaving both hands free.
Facilitate cross-winding: the tool keeps the braid stable, making windings faster, more precise and more even. No more loose or slipping knots before finishing.
Save time: this type of accessory makes it possible to tie a clean knot in just a few minutes, even at sea. An invaluable aid when fish are active and you don't want to waste a second.
Ensure a clean, solid finish: by stabilizing the entire assembly, the tool makes it possible to produce impeccable half-key ends and burn off excess cleanly, thus extending the life of the knot.

The main models available
Daichiseiko Knot Assist 2.0 : the most famous. Designed in Japan, it is compact, robust and works with all types of line. It attaches to a surface or boat ring.
Stonfo FG Knot Tool : a simpler but effective European alternative for fine braids.
Handcrafted or 3D printed models: available on Etsy or via the DIY community, these tools are sometimes very well thought-out and inexpensive.
Do I really need a tool to tie an FG knot?
No, but it helps! Many seasoned anglers know how to tie this knot by hand, by placing the rod between the legs or by wedging the braid on a support. But for beginners, or for those who want to go fast and well, an FG knotting tool is a real added value. It enables stress-free, professional results.

In conclusion, if you regularly use fluorocarbon as a leader, and want a reliable, discreet and repeatable rig, investing in an FG knot tool is an excellent idea. You'll avoid missed catches due to a poorly tied knot, and spend more time fishing than tinkering with your tackle!
