Timber Hitch: The Bowyer's Knot Explained

The timber hitch—also called the Bowyer's Knot—is a friction-based knot used in traditional bow-making to secure the lower end of a bowstring to the bottom limb of an English longbow or other self/primitive bow. Unlike a braided loop, it leaves no loose ends and can be loosened, slid, or removed without cutting the string.

How the Timber Hitch Works

The knot operates entirely by friction. The working end passes around the limb tip or nock, wraps once around the standing part, then twists back on itself 3–4 times in the lay direction of the string. When tension is applied, those dog-turns grip tighter—the harder you pull, the more securely it holds. Wrapping against the lay causes the turns to squirm sideways under load, so consistent dressing before applying tension is essential. Leave a tail of at least six string-diameters past the last wrap to prevent creep under cyclic load.

Why Archers Use It During Tillering

The timber hitch knot's adjustability makes it the preferred choice during the tillering process. A bowyer starts with a long string, checks the limb bend, then progressively shortens the effective string length—tightening the knot—until the correct brace height is reached. Because the knot slides rather than requiring re-splicing, incremental half-turn adjustments (each raising brace height roughly ¼ inch) become quick and repeatable.

Once the ideal brace height is confirmed, many traditional bowyers leave the timber hitch tied permanently at the lower nock, with a fixed braided loop at the upper limb.

String Material Compatibility

Material choice is a critical constraint. The Bowyer's Knot holds reliably on rawhide, hemp, linen, sinew, and Dacron B-50 (polyester). On modern low-stretch materials such as Fast Flight or Kevlar, it has a tendency to pull out under load. A "double Bowyer's Knot" configuration—analogous to the adjustable lower loop of a Japanese Tsuru—has been tested on Fast Flight Plus and shown to hold on low-stretch materials where the standard version fails.

Timber Hitch vs. Other String Terminations

• Timber hitch: adjustable, friction-held, suited to longbows and self-bows.
• Bowline knot: fixed loop alternative sometimes used at the lower nock.
• Braided fixed loop: standard upper-limb termination on most traditional strings.

For bowyers working with longbow construction or anyone tuning a traditional setup, understanding which knot suits which material prevents string failures at full draw. Explore bowstring construction and materials to see how string choice interacts with knot selection.
