In 1950, when Davy Wotton was a member of the Welsh fly-fishing team, his aim was to invent a knot that would enable him to tie his flies as quickly as possible (confidently and solidly, of course) so as to spend more time fishing. While this may not be a priority in the day-to-day life of a recreational angler, it's understandable that in competition it's not a negligible factor.
Beyond the temporal aspect, if Davy Wotton created and used this knot during the championships, it's because it meets 3 criteria that interest us all:
- Speed.
- Solidity.
- Ease of use.
Here's how to do it:
Step 1
Pass your nylon through the eye of your hook from front to back.

Step 2
Pass the strand over the main strand to create a loop.

Step 3
Pass the free strand back through the resulting loop (around the upstream side of the loop). A second loop is formed.

Step 4
Twisting around your thread, pass the free strand back through the loop (around the downstream side of the loop).

Step 5
Finally, pass the free strand back through the main loop one last time, making sure to turn around the upstream side of the loop.

Step 6
Moisten the knot with saliva and tighten it gradually.

Advantages :
- Very quick to execute.
- Solid.
- Wire-saving.
Disadvantages :
- Not recommended with braid.
