The nonslip loop knot ranks as one of the most useful fishing knots. Its main benefit is that it allows a plug, jig, fly or natural bait to look more natural by swinging freely on the line or leader. When fishing a frisky live bait on a single hook, for example, the loop knot provides less resistance and allows the bait to wriggle more naturally.
The loop knot really shines when used with flies, jigs and plugs. With flies, the knot improves the side-to-side swimming action of long streamers, making them look more realistic. The knot is great when fishing Clouser Minnows, which rely on a vertical jigging action to draw strikes. The same applies when hopping a crab fly over the bottom for stripers on the flats.
…the loop knot is fairly strong, testing at around 90 percent of the line’s breaking strength.
Similarly, many anglers use the loop knot when fishing leadhead jigs for fluke and seabass, as the open loop lets the jig swing freely as it’s jigged up and down. Ditto when vertical jigging with chrome-plated diamond jigs.
Lastly, the loop knot enhances the swimming action of certain lipped plugs when slow-trolled or using a stop-and-go retrieve. And when slinging pencil poppers and stick baits for stripers and bluefish, the loop knot lets these teardrop-shaped lures bobble and wobble more erratically on the surface.
The loop knot does have drawbacks, however. For one, it’s more obtrusive than other knots, which may make a difference if the fish are being line-shy, plus it tends to pick up weeds and grass. Also, there are times when you might not want the lure to swing freely on the line, such as when you need more control over manipulating your plug or when twitching a soft-plastic jerkbait through the water.
Back in the plus column, the loop knot is fairly strong, testing at around 90 percent of the line’s breaking strength. However, most knowledgeable anglers prefer to use the knot with heavier line, monofilament or fluorocarbon leaders or flexible wire tippets.
