List of friction hitch knots

A friction hitch is a kind of knot used to attach one rope to another in a way that is easily adjusted. These knots are commonly used in climbing as part of single rope technique, doubled rope technique and as 'ratchets' to capture progress on a moving rope, most typically in a mechanical advantage system such as a Z-drag. These hitches are a simple and cheap alternative to mechanical ascenders.

Pile hitch The pile hitch is easier to tie than the icicle hitch, and can be tied in the bight without access to either end of the rope.
Klemheist knot A friction hitch tied around a thicker rope that can slide while unloaded, but locks when loaded. Similar to the Prusik. Klemheist knot is a full equivalent to uni-directional Machard.
Knute hitch A knot used to attach a lanyard of small stuff to a marlingspike or other tool.
Martin hitch
