What tool is commonly used to measure the placement of the knocking point?

The tool commonly used to measure the placement of the knocking point is a bow square. This device is specifically designed to assist archers in achieving the correct height for the nocking point on the bowstring. It allows for precise adjustments, ensuring that the nock of the arrow is positioned at the optimal location for accurate shooting.

Using the bow square involves placing the square against the bowstring and the arrow rest, providing a visual indication of where the nock should be. This is critical for developing consistent shooting form and achieving proper arrow flight.

Other tools listed, such as bow wax, are used to maintain the integrity of the bowstring but do not assist with measuring the nocking point. A bow stringer is essential for safely stringing and unstringing the bow but does not serve the purpose of measuring nocking placement. A cable is a component related to the bow’s mechanics but does not provide a means to measure nock height. Thus, the bow square is the appropriate instrument for this specific task in archery.
