(Note this appears to be a later design, slightly less pretty as the original IMO) My parents bought one of these years maybe 15 years ago and I was always fascinated how he thread was so smooth, well machined and balanced that you could unwind it and it would smoothly wind back up under its own weight. When it hit the bottom the momentum would allow the inner thread to continue winding so it would bounce a couple of times. Years lately, and we don't get many cork bottles in NZ any more, but I still like to get it out occasionally to check that, yes indeed, it still does it beautifully. A simple thing, made well.
