@alice I can't say that anyone has been able to unlock my rope ties with a vibrator (yet).

Maybe I should add masterlocks that need to be unlocked in a particular sequence to undo a tie? I prototyped an escape tie with some carabiners the other week as a proof of concept, so I should be able to do it with 3 masterlocks (need to do some safety analysis for more "trick" junctions)
