Seamlessly Connect Two Fishing Lines: A Step-by-Step Guide

How to Join Two Fishing Lines Together: A Detailed Guide


Fishing is not just a hobby; it’s a way of life for many outdoor enthusiasts. Whether you’re an experienced angler or a beginner, there may come a time when you need to join two fishing lines together. It could be because you want to combine different types of lines or create a stronger connection for battling larger fish. In this comprehensive guide, we’ll walk you through various methods that will help you achieve a seamless and reliable joint between two fishing lines.

Gather the Necessary Tools

Before diving into the joining techniques, it’s essential to gather the necessary tools and materials. These include:

  • Fishing lines (the ones you plan on connecting)
  • Scissors or line cutter tool.
  • A lighter or matches (for certain joining methods).
  • Sandpaper or nail file (optional depending on the technique).

Knotless Method: The Uni-to-Uni Knot

The first method we’ll explore is known as the Uni-to-Uni knot. This knotless technique offers excellent strength and allows your connected lines to pass smoothly through rod guides.

  1. Create Overlaps: Begin by overlapping five inches of each line in opposite directions.
  2. Tie Half-Granny Knots: Take one end of Line A and make half-granny knots around Line B at least four times. Repeat this step with Line B around Line A—ensuring both knots are tied tightly but still allowing some space between them.
  3. Tighten & Trim: Carefully pull both mainlines until they meet firmly, ensuring that all knots are aligned correctly before giving them final tightening. Trim the excess ends, leaving a small tag to avoid unintended unraveling.

Traditional Method: The Double Uni Knot

The traditional method of joining two fishing lines is by using the double uni knot. This versatile knot is particularly useful when connecting lines of varying diameters.

  1. Create Overlaps: Overlap five inches of each line and hold them parallel to each other.
  2. Tie Uni Knots: Tie a simple overhand knot with one line, forming an open loop. Pass the end of the same line through this loop twice, creating an additional loop or wrap within it. Repeat this process on the other line as well.
  3. Cinch & Wet: Moisten both knots before pulling them tight—one from each side—ensuring they come together smoothly without any twisting or slipping.
  4. Tighten & Trim: Gently pull both mainlines until your double uni knot reaches full strength. Trim any excess ends, leaving just enough tag for easy handling during future retying sessions.

Alternative Method: The Blood Knot

If you prefer a more intricate yet reliable connection between two fishing lines, consider using the blood knot. This method is especially popular among fly fishermen due to its exceptional strength and neat appearance.

  1. Create Overlaps: Begin by overlapping at least six inches of each line in opposite directions.
  2. Tie Wraps Around Each Other: Starting with Line A, wrap it around Line B at least four times while maintaining tension throughout the wraps. Repeat this step with Line B wrapping around Line A in opposite rotations.

  3. Pull Through Loops:: After the wraps, carefully thread Line A through the loop formed by Line B’s initial wrapping. Likewise, thread Line B through the loop created by Line A.
  4. Tighten & Trim: Gradually pull both mainlines in opposite directions until the knot reaches its full strength. Ensure all wraps align correctly before trimming any excess ends.

Closing Thoughts

Joining two fishing lines together may seem daunting at first, but with practice and proper technique, it becomes a manageable task. Whether you choose to use knotless methods like the Uni-to-Uni knot or prefer traditional knots such as the double uni or blood knot, remember that regular testing and inspection of your connections are essential for a successful fishing experience. So grab your gear and give these techniques a try – soon you’ll be ready to face any angling challenge with confidence!
