The fishing knots you actually need

Four reliable knots cover nearly every situation: the Palomar, the improved clinch, the uni knot and the double uni for joining lines.

A lost fish is painful, and losing one to a bad knot is worse. You do not need to learn dozens of knots. Four knots, tied well, cover almost everything in freshwater fishing. Practice them at home until you can tie them without thinking.

Rules for every knot

• Wet the knot before you tighten it. Friction from tightening dry line creates heat that weakens line, especially fluorocarbon.
• Tighten slowly and firmly. Pull the knot snug with steady pressure, not a sudden jerk.
• Trim the tag end, but leave about 1/8 inch so it cannot slip.
• Test it. Give a hard pull before you cast. A knot that fails in your hands would have failed on a fish.
• Retie often. After a big fish, a snag or a few hours of fishing, cut off the last few feet and retie. Check the line for nicks by running it through your fingers.

1. The Palomar knot

The Palomar is one of the strongest and simplest knots, and it works with mono, fluorocarbon and braid. Use it for hooks, jigs and lures, and for drop shot rigs.

1. Double about 6 inches of line to form a loop and pass the loop through the hook eye.
2. Tie a simple overhand knot with the doubled line, leaving the hook hanging from the loop. Don't tighten it yet.
3. Pass the loop over the entire hook or lure.
4. Wet the knot and pull both the standing line and the tag end to tighten. Trim the tag.

Downside: large lures with several treble hooks are awkward to pass through the loop.

2. The improved clinch knot

The improved clinch is the classic knot many anglers learn first. It is quick and strong in monofilament and fluorocarbon, but it can slip with braided line.

1. Pass the line through the hook eye and pull through about 6 inches.
2. Wrap the tag end around the standing line five to seven times. Use fewer wraps for heavy line, more for light line.
3. Pass the tag end through the small loop just above the eye, then back through the large loop you just created.
4. Wet it, pull the standing line to cinch it tight, and trim.

3. The uni knot

The uni knot is extremely versatile. It works for tying on hooks and lures, for attaching line to a reel spool, and for joining two lines (see the double uni below). Leave it slightly loose before the final tightening and you get a loop that gives a lure more action.

1. Pass the line through the eye and double it back alongside the standing line.
2. Bring the tag end back toward the eye to form a loop lying against the doubled lines.
3. Wrap the tag end around the doubled lines and through the loop five or six times.
4. Wet it and pull the tag end to snug the wraps, then pull the standing line to slide the knot down to the eye. Trim.

4. The double uni knot (joining two lines)

Many anglers use braid for its strength and sensitivity, with a fluorocarbon or monofilament leader at the end because it is less visible and resists abrasion. The double uni is the easiest reliable way to join them.

1. Overlap the ends of the two lines by about 8 inches.
2. With one line, tie a uni knot around the other line. Use about 6 to 8 wraps for braid and 4 to 5 for mono or fluorocarbon.
3. Repeat with the other line, tying a uni knot around the first.
4. Wet both knots, tighten each one separately, then pull the two standing lines in opposite directions so the knots slide together. Trim both tags closely.
