How to tie a hammer proof nymph for rivers

11th October 2019

Fishing with nymphs in the river is one of the most common and productive methods used in fly-fishing.
You don’t need to wait for the hatch, you can fish all day long and all year round, even in the winter.
It is as well much more profitable than dry-fly fishing, trouts get 90% of the food under the water surface.

The nymph in this post will be quite heavy, this is the reason why it is good for rivers and streams but not for lakes, where you need to use light-weight nymphs to not lose the imitative swimming property.
In rivers and stream, sometimes, you have to go down quickly, get the bottom as fast as you can, this nymph is great for this purpose.

The best colour for the nymph is, without doubt, olive.

Olive colour imitates a wide range of aquatic insects, especially of the Beatis, a genus of mayflies. These species are distributed everywhere, especially in Europe and North America.

What do you need:

  1. Hook Size 10 to 18 (Buy it on Amazon)
  2. Tungsten Bead (Buy it on Amazon)
  3. Vynil-Rib, it is a translucent half-round material used for segmented body
  4. Ice Dubbing (Buy it on Amazon)

Step 1: cut a string of Vynil-Rib, hold it between thumb and forefinger.
With a lighter slowly heat up the material, it takes ½ second to get warm enough, don't burn it!


Step 2: With the thumb and forefinger press the warm part of the Vynil-Rib to make it flat, step 1 and step 2 are made to improve the fly silhouette.


Step 3: fix the thread on the hook and wrap it till the hook curve.


Step 4: Place the pressed part of the Vynil-Rib on the hook and with few nice and strong turns fix the Vinyl-Rib on the hook, try to make a slight V shape with the thread.


Step 5: Hold firmly the Vinyl-Rib, pull it and start to wrap it around the hook shank, until the tungsten bead. This step is the most important, make sure the material is not loose, it has to be fixed. Secure it with the thread and trim the excess part.


Step 6: With the dubbing needle apply some varnish on all the fly, both tungsten bead and Vinyl-Rib body, this cover will make your nymph more durable against stones and trout teeth. Let it dry.
(You can use UV resin, better if thin, to make this step faster)


Step 7: After have waxed the thread put on it some ice dubbing.


Step 8: Wrap it and finish the fly, with the dubbing needle pull out few strings of ice dubbing, they will make some movement in the water. Now you are ready to catch a lot of fish with this fly before throwing it.


Tie it in different colours, they all work well.

This fly is really effective all year round, it worth a try.
The Vinyl-Rib translucent property is useful if you want to get different shades.
If you tie the same fly using black thread the shade will be darker, on the other hand, if you tie it with white thread the shade will be lighter.
