How to Tie a Nanofil Knot

The Nanofil fishing knot, aka the Berkley Nanofil Knot, is made from gel polyethylene, and it is known for its super thin profile, strength, lack of stretch, and zero memory. It is basically a Palomar knot that includes a double overhand knot rather than the single one, so it is also known as the double Palomar knot. 

It is one of the few fishing knots that can be used to tie terminal tackle with super braids such as the Spiderwire. 

Nanofil Knot Tying Instructions


Step 1

Double over at least six inches of fishing line and thread the end of the loop through the hook eye.

Step 2

Make a loose overhand knot making sure the hook hangs from the bottom.

Step 3

Hold the overhand knot between your forefinger and thumb and then pass the loop over the hook before sliding the loop above the eye.

Step 4

Pull-on the tag and the standing end of the fishing line to tighten the Nanofil knot on the eye. Make sure that the knot doesn’t hang on the shank.

Step 5

Cut off the excess tag end to close the knot. 

Tie these knots several times to get the hang of them and to make sure they don’t break. 

Jansik Special vs Nanofil Knot

Both the Nanofil (Berkley or Double Palomar) and the Jansik Special knot can be tied to a lure or the eye of a hook quickly. However, the former can retain 15% more fishing line strength compared to the latter. 

On the other hand, the Jansik special can take a lot more abuse in comparison, especially when you are trying to catch aggressive fish. Tying these knots is not difficult either. 


  • Make sure you leave at least a few inches of the tag end of the fishing line after making the wraps on the Berkley knot. The longer the tag end, the fewer chances that it will slip into the knot.

This one can be used for effortless and long casting with reduced drag. Since it has zero memory and is quite flexible, it does not snag the line and offers a clean cast. It is the most useful for anglers who require a sensitive knot that can help them feel subtle bites. 

So they can spend more time fishing and less time untangling the line. You can tie a braid to Nanofil knot, a Nanofil leader knot, or a Nanofil to the mono knot as well.

Advantages and Disadvantages
