(2020), whose findings appear only as a paraphrase in the page text. The reef_means column says whether the source's reef knot is the square knot or a square knot with a bight (one end doubled back into a bight; not the knot Verrill's Fig. 14 captions Slipped square knot). Two rows record what no source covers and this site's safety rule. Read 2026-11-14.",
