Non-slip Loop (Kreh Loop)
A loop knot leaves a gap between the line and the fly or lure. The result is a wider, freer swing on a streamer and a sharper kick on a jerkbait. Lefty Kreh's version is the standard.
Tying it
1. Make an overhand knot in the standing line about 8 inches from the tag.
2. Pass the tag through the eye, then back through the overhand loop.
3. Wrap the tag four times around the standing line above the overhand.
4. Bring the tag back through the overhand, exiting the same side it entered.
5. Wet. Pull standing line and lure simultaneously; the knot seats and the loop sets.
Loop size
Aim for a loop about the width of the fly's body. Too small and you lose the action; too large and the loop fouls on weeds.
Where it shines
- Articulated streamers (sex dungeons, mini lap dancers).
- Soft-plastic jerkbaits where the kick depends on a fulcrum.
- Heavy nymphs in fast water; the loop lets the fly tumble naturally.
When not to use it
- Light tippet under 4X. The loop knot lacks the clinch's friction and can slip.
- Soft-bodied flies (small dries) where weight is so low the loop adds no advantage.
