Klemheist knot

This knot is similar to the Prusik knot knot and the Klemheist knot.

The two main alternatives are the Bachmann knot and the Klemheist knot (see also the Tarbuck knot).

The 'Klemheist knot' (or 'Machard knot') is a type of friction hitch, used as part of a system to ascend or descend a rock climbing rope.

The klemheist knot or Machard knot is a type of friction hitch that grips the rope when weight is applied, and is free to move when the weight is released.

A prusik, Klemheist knot, or Bachmann knot may be used as safety back-up, also called a "third hand," and is used as a back-up in the case of the abseiler losing control of the abseil.

Upon examination of the icicle hitch, one finds that it operates under the same principle as the Klemheist knot and is in fact the same knot tied only with a bight in the end instead of the more common short loop used for climbing.
