A Turk’s head knot is a decorative knot with a variable number of interwoven strands, forming a closed loop. The name is used to describe the general family of all such knots rather than one individual knot. While generally seen made around a cylinder, the knot can also be deformed into a flat, mat-like shape. The knot is used primarily for decoration and occasionally as anti-chafing protection. A notable practical use for the Turk’s head is to mark the “king spoke” of a ship’s wheel; when this spoke is upright the rudder is in a central position. The knot takes its name from a notional resemblance to a turban though a turban is wound rather than interwoven.
The Turk’s head knot is used as a woggle by Scout Leaders who completed their training course and were thus awarded with the Wood Badge insignia.
