Attaching the fly to the tippet is the one knot in fly fishing you will tie dozens of times per trip. When a fly breaks off, when you change patterns, when you want a different hook size — the fly-to-tippet knot is the constant. Tying it reliably is worth mastering before anything else.
Knot 1: Improved Clinch Knot — The Standard
The Improved Clinch Knot is the most widely used fly-to-tippet knot. It’s reliable, adjustable by wrap count to different tippet sizes, and quick to tie once learned.
How to tie:
- Thread the tippet through the hook eye. Pull 6–8 inches of tag end through.
- Make 5 wraps. Hold the hook and the tag end between your thumb and forefinger. Rotate the hook (or the tag end) to wrap the tag around the standing line 5 times. Count: one, two, three, four, five. For 0X–2X heavy tippet: 4 wraps.
- Thread the tag through the near loop. The near loop is the small triangular opening between the eye and the first wrap. Pass the tag through this opening.
- Thread the tag through the large loop. Pass the tag back through the large loop you just created by going through the near loop. (This is the “improved” step — the basic clinch knot stops after step 3.)
- Moisten and pull. Wet the knot thoroughly. Pull the standing line steadily while holding the hook — the wraps should compress against the eye in a neat, even barrel.
- Trim the tag to 1/8 inch.

Wrap Count Guide
| Tippet Strength | Wraps |
|---|---|
| 0X–2X (12–15lb) | 4 wraps |
| 3X–5X (4–8lb) | 5 wraps |
| 6X–7X (2–3.5lb) | 6 wraps |
More wraps in lighter tippet; fewer in heavier.
Knot 2: Davy Knot — For Small Flies
Developed by Welsh fly fisherman Davy Wotton, the Davy Knot is the smallest and fastest fly attachment available. Preferred for hook sizes 18 and smaller, where the Improved Clinch’s barrel becomes too large relative to the hook.
How to tie:
- Thread tippet through the hook eye, 6 inches of tag
- Pass the tag end over the standing line (creating a loop)
- Pass the tag end through the loop once
- Moisten and pull
That’s it — two movements. The result is a very small, clean knot that doesn’t crowd tiny hook gaps.
Strength: Slightly lower than the Improved Clinch (about 80–85% vs. 90–95%) but adequate for the small fish and light tippets typical with small flies.
Knot 3: Non-Slip Loop Knot — For Active Flies
A cinch knot attached to a streamer or wet fly limits the fly’s ability to swing and pivot at the hook eye. The Non-Slip Loop Knot creates a small fixed loop that allows the fly to move completely freely.
How to tie:
- Tie a loose overhand knot 6 inches from the tag end
- Pass the tag through the hook eye
- Bring the tag back and pass it through the center of the overhand knot
- Make 4 wraps around the standing line (above the overhand knot)
- Pass the tag back through the overhand knot from the same side it exited
- Moisten and pull both the standing line and tag end
- The two knot sections lock against each other, fixing the loop size
Why this works: The finished loop size is set when you pull tight — it cannot collapse or slip larger. The fly hangs at the end of the loop and can pivot 360 degrees at the hook eye.
Use for: Streamers, sculpin patterns, Wooly Buggers, large wet flies, and any fly that benefits from free, natural movement.
Knot 4: Uni Knot — Versatile Alternative
The Uni Knot can substitute for the Improved Clinch in all fly-to-tippet applications. Some anglers prefer it because the loop formation gives a slightly more visual way to count wraps on light tippet.
How to tie for fly attachment:
- Thread tippet through eye, double tag back alongside standing line
- Make 5 wraps through the resulting loop
- Moisten and pull
Strength is comparable to the Improved Clinch.
Common Mistakes When Tying Fly to Tippet
Tying dry. The most common reason for knot failure. Always wet the knot before pulling. Light tippet generates less friction than heavy line, but the delicate fibers are more sensitive to any heat damage.
Threading through the wrong side of the eye. Some hooks have turned-up or turned-down eyes. Always thread from the outside (convex) curve of the eye toward the inside — threading the wrong direction puts the knot on the wrong side of the eye and changes the fly’s riding angle.
Not checking the fly position after tying. After cinching, the fly should ride straight on the hook — not cocked sideways. Pull the fly by the bend while holding the standing line to confirm the tippet enters the eye straight.
Tearing the tag instead of cutting. Torn tags leave thin fiber ends that can wick water and cause the fly to sink faster than intended (bad for dry flies). Use sharp nippers for a clean cut.
