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.
Why it’s cool: Easy to tie, can be tied with one hand, and is useful in many situations.
Red Flags/Rules: Don’t leave slings girth-hitched to your harness belay loop for extended periods of time.
