Knots are a fascinating topic, and a recurring one on HN, for example: https://news.ycombinator.com/item?id=10200917 https://news.ycombinator.com/item?id=10200917 https://news.ycombinator.com/item?id=26867300 https://news.ycombinator.com/item?id=26867300 Many years ago, I learned about Ian's secure knot (https://www.fieggen.com/shoelace/secureknot.htm https://www.fieggen.com/shoelace/secureknot.htm), a shoelace knot, which I have used since then. It just never accidently opens but still is simple to tie and also simple to open on intention.
