 I've seen it many a time and he winds, he winds,
After thirteen times he's got a hangknot.The Hangman's knot is visually indistinguishable from a Uni Knot, but the two are entirely different knots.The Uni Knot is used in rock climbing, sailing, fishing, and many other outdoor and recreational use as it holds tight and doesn't slip, unlike a Hangman's knot which needs to slide.
