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 Blake's hitch is a friction hitch commonly used by arborists and tree climbers as an ascending knot. Unlike other common climbing hitches, which often use a loop of cord, the Blake's hitch is formed using the end of a rope. Although it is a stable knot, it is often backed up with a stopper knot, such as a figure-of-eight knot, for safety.
A friction hitch tied around a thicker rope that can slide while unloaded, but locks when loaded. Commonly used to back up belays. Similar to the Prusik only in function. French Prusik is equivalent to bi-directional Machard. Bachmann hitch: Blake's hitch: A friction hitch commonly used by arborists and tree climbers as an ascending knot.
The rope to be pulled is passed through a pulley, and a Prusik is tied on the loaded side. When the rope is pulled, the Prusik rides against the pulley, and the rope slides through it; but when the rope is relaxed, the Prusik slides away from the pulley and grabs the rope. Thus, the combination acts as a ratchet (or Progress Capture Device (PCD)).
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."
