The Davy knot is the creation of Davy Wotton, a Welshman relocated to Flippin, Arkansas, who has been fly fishing since the 1960s. Many anglers love the knot because it’s quick to tie and is quite small. These videos from Tightline Productions show you two versions, which you can try on the water. I know several anglers who simply swear by the Davy knot and use it for all dry flies and nymphs.
For more information on Davy himself, check out his elaborate website.

The Davy Knot (bottom) is considerably less obtrusive than the standard Clinch Knot.
I started using this last year after Tightlines did their video. So far it’s proven to be just as strong as the clinch and just a bit easier to tie.
I keep hackle pliers ringed to my nippers at the end of a zinger too lol
Lol
Significantly less strength in the larger tippet sizes, but 4x and down less of a disparity, I like this for small olives midges, tricos etc.
Agree that the Davy knot is good for smaller diameter tippet 4x and down. Slippage is a problem with much larger. Admit I haven’t tried the double, but intend to try both in freezing weather when dexterity is a challenge with arthritic fingers.
i’m hoping someone could help me , i inherited a 8′ berkeley hunter series no other markings i’m wondering the weight on this
Is there a way to modify the knot to include a loop for better motion of streamed, etc.? I’m assuming there is “knot”.
I use a uniknot to get movement in my fly . It also collapses on hook set so you get a little bit of a shock absorber . It is an involved knot to tie . Like all knots it is terminal tackle so you want to check your knot from time to time.
instead of hackle pliers I use my forceps to do the same thing.
That’s the only knot I use
Other than the use of “loop” knots for motion, the Double Davy knot is the ONLY knot I use. I have never had a single problem of any kind.
My dyslexia makes it hard to remember the Davy. I can remember the snell knot, Trilene, improved clinch, perfection, blood, Bimini, but not the darn Davy!
I wince every time I see an experienced (often celebrity) angler making the old 5 twist clinch.
The clinch is the tricycle of fishing knots; perfect for the beginner.
The Double Davy is the Tour de France racer – the best tippet to fly knot available to the serious angler.
Here’s the hands-down, fastest way to tie the Double Davy knot using the “Pinch Method”.
