The Trace-Eight (or Trace Figure-Eight Knot) Your tie-in knot, the one that connects you to the end of the rope, is the knot to learn first, and is the only knot you'll use every time you rope up. Climbers use various knots to tie in, but the Trace-Eight is the easiest to learn and the least likely to untie itself.

A single half hitch is one of the most basic types of knots. It is also referred to as an overhand knot. Wrap the end of a rope around an object, cross that working end on itself, and pass it through the loop created (think about the first thing you do when tying your shoes).

A bend is a type of knot used to join two lengths of rope. Bends are used in a variety of situations, including climbing, sailing, and securing loads. They are classified based on their ability to be tightened or released, their resistance to slipping, and their strength.
