Named after Berkley’s Trilene monofilament, the Trilene knot is a stronger variation of the commonly used improved clinch knot. Tied carefully, it tests at close to 100 percent of line strength. I often use it for tying lures or hooks to nylon monofilaments testing from 4 to 12 pounds. Tightening this knot with heavier lines is too difficult.
 Put about 6 inches of line through the hook eye. Then put the tag end through the hook eye a second time, forming a small double loop. Hold the loop and hook eye with the thumb and index finger of your left hand.
 Turn the tag end around the standing line five times (in front of the loop). Then put the tag end through the double loop.
 Moisten the line copiously with saliva to make tightening easier, then pull the standing end firmly to seat the knot.
