The Trilene knot provides a reliable connection that tests at about 95 percent break strength. Although this knot works best with monofilament, threading the tag end back through the large loop also secures superlines.

1. Run the line end through the eye, reinsert the line back through the eye, forming a double loop.
2. Wrap the tag end around the standing line 5 to 6 times.
3. Pass the tag end through the double loop at the eye.
4. Moisten the knot, hold the tag end firm, and draw the mainline tight.
