David Lienbenberg (@jumbosailing) does professional #sailing and brought his #diamondknot #softshackles for us to break test. Then we compared them to the #buttonknot that has more strength because it makes the diameter bigger for the noose. The button knot was getting 25% to 30% more strength than the diamond knot. 2mm and 1/8" (3.2mm) were tested in this video.
