Perfection Loop
Also known as:Angler's Loop

Description
A strong and compact loop at the end of a line, popular in fly fishing and general use. Two interlocking loops are formed and the tag end is passed between them to lock the knot.
Common Uses
Creating a fixed loop at the end of a leader for attaching flies or tippet loop-to-loop; general purpose fixed loop.
When to Choose This Knot
Choose this knot when you need a loop that can connect to a post, ring, hook, carabiner, handle, or another rope part. Loop knots differ in whether they stay fixed, cinch down, or remain easy to untie after loading.
Safety Notes
- Confirm whether the loop is intended to be fixed or sliding before applying load.
- For climbing or rescue, use only knots and rope systems approved by your training program or local standard.
- Check that the standing part, tail, and loop are oriented correctly before loading.
How to Tie
- 1Form a loop in the standing part near the end.
- 2Form a second loop beside the first, with the tag end passing behind the standing part.
- 3Bring the tag end back between the two loops.
- 4Pull the tag end and the standing end to dress the knot. The loops collapse into a V-shape.
Common Mistakes
- Confusing a fixed loop with a noose or running loop.
- Loading the loop from an unintended angle.
- Skipping a backup knot where the application requires one.
