In contrast to many other knots, the Perfection Loop or Angler’s Loop is useful well beyond fishing. A favorite of climbers and other outdoor enthusiasts who need a fast, fool-proof method for producing a secure loop, the Perfection Loop is a must-know knot.
And for fly anglers, this is nothing short of an essential. Not only does it make quick work of the job of attaching new leader to your fly line, but it’s also great for attaching flies because it allows them a loose, life-like action.
In larger materials like rope or bungee cord, the Perfection Loop knot can be tied in hand to create a secure free-standing loop. For fly applications, it may be easier to use an alternate method.
We’ll provide instructions for both.

The Perfection Loop is one of those knots that’s hard to fault. It’s very good at what it does, and it’s faster and easier than the alternatives that get the same job done.
Ideal for allowing quick leader changes on looped fly line, the Perfection Loop is a staple of fly angling and well worth the almost minimal trouble of learning it. And though it isn’t as slender as the Nail Knot, that’s not much of a bother in fly casting.
The only other issues you might have with the Perfection Loop Knot is that once you’ve jammed this knot down under pressure, you’ll have a devil of a time untying it if you need to. That’s not ever a concern with fly leader, but it can be a problem in rope or paracord.
Fly line and monofilament or fluorocarbon leader love to bite against themselves, producing plenty of knot-holding friction. Scientists and engineers call this trait a “high coefficient of friction.”
What that means in practice is that these lines love to hold a properly executed knot.
A well-tied Perfection Loop will hold in fly line, mono, and fluorocarbon, allowing you to use this knot freely in fly applications.
However, the Spectra and Dyneema fibers that braided superlines are woven from are simply too slick to hold in this knot. And as good as the Perfection Loop is, it will simply slip free under pressure if you try it in braid.
If you’re looking for a line-to-line connection knot for braid, try the Triple or Quadruple Surgeon’s Knot.
The Perfection Loop Knot is very secure when tied properly, making it an excellent choice for fly anglers. Failures are few and far between if you avoid the following mistakes:
