Need-to-Know Climbing Knots: Double Fisherman’s

If you’re going to be a rock climber, you don’t necessarily need to know how to tie your shoes (as long as you wear Velcro slippers), but there are seven essential knots you’ll want to know. There are dozens of knots that might be worth learning as a climber, but for the most part, you can get up and down any climb on Earth with just these basic, essential knots—The Figure-8 Retraced, Girth Hitch, Clove Hitch, Munter Hitch, Double Fisherman’s, Prusik and Euro Death Knot.

Know them, learn them, and practice them until you can tie them in your sleep.

Double Fisherman’s

What is it: A knot used for tying two ends of a cord or rope together. Use this knot to create a cordellette (a piece of cord tied into a loop) or to create a prusik.

Why it’s cool: Reliable, safe knot for joining two ends of a rope or cord together.

Red Flags/Rules: This knot will weld itself shut over time, effectively making it impossible to untie. This knot is only to be used for joining two pieces of rope or cord. To join two pieces of tubular webbing, use a water knot (not covered here).

How to Tie it

  • Set the two ends together, each pointing in opposite directions.
  • Wrap one end around both ropes two times.
  • Pass this end back through the loops that these turns created and pull tight.
  • Do the same on the other side: wrap the other end two times around both ropes.
  • Pass this end back through and pull tight.
  • Make sure both sides of the knot sit against each other (if they don’t, untie one end, and try wrapping it in the other direction).
  • Pull on both ropes tight to cinch the two knots against each other.
