32. Angler’s Loop

Also known as: Perfection Loop

Tied in any kind of small stuff, this fixed loop will not slip. It works well
with monofilament, bungee cord, and regular cordage. It is difficult to tie in
heavier rope but it holds well in that too—so well, in fact, that you should
consider it fairly permanent, no matter the type or size of cordage. Usually
tied on the working end, it can also be tied on the bight.

Uses: fishing leaders, tippets and hooks, bungee cord, bungeed tent fly tie-downs
Pros: holds well in any material

Cons: very difficult to untie; hard to fair and tighten in heavy rope
