As a ship captain I must say these are excellent choices but I believe it’s also important to point out the most dangerous and improperly used knots. Number one on that list is the square knot which, according to knot expert Philippe Petit, has caused more injuries and deaths than all other knots combined. I also want to give a shout out to my favorite source of knot related information and research: the international guild of knot tyers, https://www.igkt.net, which provides free youth memberships.
