Join two ropes with a double fisherman's bend
Two ends that each wrap around the other and lock together. Climbers use it to join cord into a loop that won't come undone.

- Lay the two rope ends side by side, overlapping, pointing in opposite directions.
- Wrap one end twice around both ropes, then tuck it back through those two turns and pull tight.
- Do the same with the other end: two turns around both ropes, back through, pull tight.
- Pull the two ropes apart so the two knots slide together and sit snugly side by side.
Tip: It can jam so tight it's nearly impossible to untie, so use it where you want a permanent join. For anything your life depends on, leave long tails and get it checked by someone trained.
Try it now: Join the two ends of a shoelace into a loop, then pull the loop hard from inside.
