As the name suggests, this knot is often used by lumbermen and arborists for attaching ropes or chains to tree trunks, branches, and logs. [3] [5] For stability when towing or lowering long items, the addition of a half-hitch in front of the timber hitch creates a timber hitch and a half hitch, [6] or known as a killick hitch [2] when at sea.

The similar ABoK numbers are in ABoK's unique "Chapter 22: Hitches to Masts, Rigging and Cable (Lengthwise Pull) [5] 1st paragraph reads: "To withstand a lengthwise pull without slipping is about the most that can be asked of a hitch. Great care must be exercised in tying the following series of knots, and the impossible must not be expected."
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.
How the rope is sent down a shaft has great bearing on the type of single-rope technique used. In general, while rope-walking techniques may be very effective for climbing long unobstructed pitches, they prove less versatile in cases of awkward passages and complex rope rigging with re-belays used to avoid hazards such as loose rocks ...

The climbing rope is then hauled over the branch by pulling on the throw line. The line is anchored to the trunk or to the high limb itself by running one end through a closed bight made in the other end. The climber then ascends the rope (using a set of friction hitches or mechanical ascenders) to obtain the desired limb. With practice, this ...
