Top Fly Fishing Knots You Must Know

Mastering fly fishing knots ensures your hard work pays off and enhances your fishing success.

Getting good at fly fishing means mastering various skills. Becoming proficient in these skills is one of the sport's enjoyable aspects, and anglers with a solid understanding of the fundamentals will advance quickly and succeed more when fishing.

Casting is the skill that holds the most importance. Nevertheless, a skill that many anglers appear to be overlooking is the ability to secure fly fishing knots properly. 

You can spot the fish, choose the proper fly, execute a flawless cast, feel the bite, and set the hook. However, if one knot comes undone, all your hard work will be for nothing.

If you have ever gone fishing with a skilled guide, then you know that they will always tie the knots for you securely. Even beginner anglers should master the art of tying strong and dependable knots!

Read this guide and discover the top fly fishing knots you must know for a successful adventure.

Backing to the Reel Spool

First, you need to address your backing. If you're starting with an empty reel, this should be your priority, as it will support you when you hook a big fish that runs with your whole fly line.

You need support to occupy the additional room in your reel because your reel is meant to accommodate a fly line in addition to a specific amount of backing. Filling the reel arbor with the proper backing is necessary, even if you only intend to catch small fish. If not, your fly line will wrap tightly around the small spindle, making it hard to untangle and use effectively.

Certain reels feature a marking on the interior of the spool frame that shows the appropriate amount of backing to fill the reel. If not, add liquid until the container is approximately one-third to half full.

Putting backing onto a reel can be tedious. You must wound the backing tightly and evenly, moving back and forth across the width of the reel arbor. 

When you loosely wind coils of backing at the bottom of the arbor and wind tighter layers on top, the tight coils will get stuck underneath the loose coils, causing a tangle that can hinder your reel. So, wind your backing onto the reel correctly to prevent future issues.

Arbor Knot

The arbor knot is an easy and efficient fly-fishing knot. It attaches your backing to your reel. If a fish pulls enough line that you're at your arbor knot, you'll likely lose the fish and your line. 

The purpose of the arbor knot is to help you wrap your backing around your reel. But, it's best not to depend solely on the knot to secure a fish. You must include enough backing and adjust the drag to prevent the arbor knot from failing.

How to Tie An Arbor Knot

  1. Wind the fishing line around the arbor.
  2. Create a loop around the main part. Thread the tag end through it.
  3. Secure the knot and loop the tag around itself until it reaches the end.
  4. Put it through the circle to make it more secure.
  5. Finally, pull firmly to tighten the second knot to the first one and fasten both to the arbor.

Backing to Fly Line

Once you have wound your backing, it's time to attach it to your fly line. You can use either a loop system or a nail knot, but a loop system will allow you to switch between lines without cutting your backing or fly line. 

Bimini Twist Knot

The Bimini Twist is a standard loop fly fishing knot for saltwater fishing and fishing for big, strong fish. The Bimini twist fishing knot maintains nearly the line's original strength. Therefore, it is referred to as a 100% knot. 

It is very powerful and efficient, so tying this fly fishing knot can be a bit more complex than others, but it's not overly difficult. You can trust this knot in any fly-fishing situation!

How to Tie a Bimini Twist Knot 

  1. Loop around the support and wrap the tag end 20 times.
  2. Draw the turns tight, pulling the ends apart.
  3. Next, slip the end over the turns by pulling it toward the backing.
  4. Pass it around the loop's upper arm, then pass it through the small loop below and bring it up.
  5. After doing so, tighten and wrap around the entire loop four to five times.
  6. Finally, pull to tighten and trim off any excess.

Attaching Loops

Two primary methods will help you connect your loop knot to your fly line. The initial step is to place the loop knot through the fly line loop and wrap it around the fly line spool. You'll find that the loops fit together seamlessly. 

Another method is to repeat this process by using two loops to secure the backing tightly onto the fly line loop. This prevents the backing from cutting into the fly line too deeply and provides extra support.

Butt Section to Fly Line

Now it's time to connect your leader to the fly line. Typically, a heavy monofilament piece is connected to the fly line before attaching the leader to the butt section. If you lack a distinct butt section, you can identify the final part of your leader as the butt section.

There are two primary methods for connecting the butt section to the fly line: either by directly tying it on or using a loop knot.

Nail Knot

A nail knot penetrates your fly line and provides a neat connection between your butt section and the fly line. Tying this fly fishing knot is a bit more complex, but you can utilize a nail knot tool to make things easier.

The nail knot is useful in connecting two lines of varying sizes. It links the backing to the fly line and the fly line to the leader. The knot gets its name from a nail initially used as a reference point for tying it. However, replacing the nail or needle with a slender hollow tube or straw will simplify the tying process.

How to Tie a Nail Knot

  1. Make five turns with the leader, holding the ends of the two lines with the tube in between.
  2. Insert the leader into the tube at the 6th turn.
  3. Then, take it out of the other end.
  4. Remove the tube by sliding it down.
  5. Finally, tighten the fly fishing knot by pulling both ends. Cut off excess if there's any.

Perfection Knot

A perfection knot is a simple loop fly fishing knot you can do easily. The sturdy loop is clean, and the line's standing end comes out of it in a straight direction. 

How to Tie a Perfection Knot

  1. Make a loop with the tag end.
  2. Loop again and bring the tag end to the middle of the two loops.
  3. Pass the second loop through the first one.
  4. Hold and pull in both directions to tighten.
  5. Cut off excess tag end if there's any.

Leader to Tippet

Connecting sections is essential to form your leader. You must also incorporate tippet material into your leader. 

Double Uni Knot

Most fly anglers are not very familiar with this fly-fishing knot. But it's great for joining two lines of varying or similar strengths. It ties the uni knot with the line doubled twice at both ends. Both salt and freshwater anglers use it. 

It can join a fluorocarbon leader with a braided mainline and is an excellent mono-to-mono knot. You can use it for both salt and freshwater fishing. This technique is also great for attaching a supple-wire bite tippet to your leader. 

How to Tie a Double Uni Knot

  1. Overlap the ends of the lines to join them. 
  2. Take the end of the line from the left and double back. 
  3. Make 3 to 4 wraps around both lines and through the formed loop. Then, tighten it by pulling the tag end.
  4. Repeat this with the end of the line on the left, making the same number of wraps unless you are tying with a braided line. In this case, you should double the number of wraps.
  5. Now that you have tied two Uni knots, you will pull the standing lines in the opposite direction, sliding the two knots together.
  6. Finally, clip the ends close to the knot.

Blood Knot

The Blood knot is widely known and practical. It is smooth, relatively simple to fasten, and ideal for joining two leader/tippet pieces of the same diameter. Over the years, people have devised several quick methods to tie this fly fishing knot, incorporating toothpicks and/or their mouths for assistance. 

How to Tie a Blood Knot

  1. Overlap the ends of the lines to join them. 
  2. Twist one around the other, making five turns. Bring the tag end back between the two lines.
  3. Repeat this with the other end, wrapping the same number of turns in opposite directions.
  4. Slowly pull lines in opposite directions. 
  5. The turns should wrap and gather. Lastly, clip the ends close to the knot.

Tippet to Fly

The final step is adding your fly. Again, there are two main ways: a loop or a standard knot.

Improved Clinch Knot

The improved clinch knot does an excellent job of attaching the fishing line securely to a hook, swivel or lure. This famous fly fishing knot outperforms the standard clinch knot because of an additional tuck in the final loop, making it ideal for securing large fish.

How to Tie an Improved Clinch Knot

  1. Pass the working end through the hook's eye.
  2. Wrap it five times around the standing line.
  3. Pass it through the first loop.
  4. Pass it under the bigger loop you just created.
  5. Finally, tighten the knot by pulling on both ends.
