The timber hitch is a knot used to attach a single length of rope to a cylindrical object. Secure while tension is maintained, it is easily untied even after heavy loading.
Usage
As the name suggests, this knot is often used by lumbermen and arborists for attaching ropes to tree trunks, branches, and logs. 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, or known as a killick hitch when at sea. A killick is "a small anchor or weight for mooring a boat, sometimes consisting of a stone secured by pieces of wood".This can also prevent the timber hitch from rolling.
Tying
To make the knot, pass the rope completely around the object. Pass the running end around the standing part, then through the loop just formed. Make three or more turns (or twists) around the working part. Pull on the standing part to tighten around the object. A common error in tying can be avoided by assuring that the turns are made in the working part around itself.When making the hitch in laid rope, the turns should be made with the lay of the rope, that is, in the same direction as the twist of the rope
