US Patent 9453700 Method and apparatus for aligning arrow nocks

An alignment tool may be used to align a nock with respect to an arrow having vanes. The alignment tool may include a body, a connection member extending from the body, and indicating surfaces that are spaced around the outer surface of the alignment tool body at a relative angular orientation that matches the angular orientation of the arrow vanes. The connection member may be attached to the nock and then both the tool and the nock may be rotated with respect to the arrow to align the nock with respect to the arrow by aligning the indicating surfaces with respect to the vanes.
