I have used this "half" double fisherman knot as a breakaway lanyard knot also. I have found it slips best using stiff solid core line like a round shoelace better than it slips using Paracord. It seems like the looser Paracord jacket sometimes binds.<br><br>Another knot that I have used as a breakaway is the hangman's noose. Sounds like a bad idea, but you wear it so that the sliding part of the cord is short and free to pull out of the loops.<br><br>This diagram is from Chris Reeve's site.<br><br>You place the item you want to carry in the top loop static bight in picture 1 (right hand side).<br><br>Then start the coil around a big loop with a circumfrence you want to hang around your neck.<br><br>Adjust the coil tension so that the free end has the correct tension to retain the item but still slide freely out of the nest of coils. Make this sliding end as short as possible so it will slip out of the coils not tighten the loop. Try it, and adjust to suit, also use at your own risk.<br><br>
