What is the purpose of the serving string on a bowstring?

The serving string on a bowstring is primarily used to extend the life of the bowstring. This section of the bowstring wraps around the strands of the main string at specific points, particularly at the nocking point and where the bowstring contacts the bow. Its purpose is to provide extra protection against wear and tear caused by the nocking of the arrow and the movement of the string under tension. By reinforcing these high-stress areas, the serving helps to maintain the integrity of the bowstring, preventing fraying and potentially prolonging its lifespan. This function is essential for ensuring consistent performance and safety during archery practice and competition.
