In reply to Jamie B:
This is quite worrying, especially as more than one poster on this thread seems willing to defend this method.
It isn't clear to me from the diagram in the link, or from other posters' comments, whether the dead rope is immediately locked off when the climber falls, or whether the fall is actually held in the "slip-slap" position. If the former, then surely it would be obvious, to Yanks and Brits alike, that a method that keeps the dead rope ready in the locked off position most of the time must be preferable. If it's the latter then frankly I'm amazed there aren't more accidents. You might as well dispense with the belay plate and just run the rope through the karabiner!
I've seen this method tried on a few occasions, almost invariably by people who have been out of the game for many years and are regressing to the method they were taught back in the 60's or early 70's with a waist belay (with which, as with an Italian hitch, it is a sound method as others have said). I've always politely put them right, and they've usually been very grateful.
> It looks deeply counter-intuitive, and breaks several of the "rules" mentioned in the original video BUT if a climber has been using it successfully for years and has held numerous falls with it, should it be seen as lethal and should they be asked to adopt a method that they may be less comfortable with?
I know Americans are supposed to be hotter on individual freedom than us Europeans, but this seems to be taking things a bit far. On my two or three climbing outings with American friends, in New Hampshire and the Gunks, no-one's tried to belay me this way, and I would certainly have said something if they had. As it happens these Americans probably had a stronger ethic of checking each other and pointing out short-comings in safety techniques than my British climbing partners.
> I've experimented with it, out of professional curiosity, and would have to say that it works better than you might expect, although I'm not going to be switching to it anytime soon! My suspicion remains that it was developed at a time when devices like Sticht plates and Tubers were the norm - these are much grippier than a modern plate and more or less require live and dead rope to be paralell for there to be any movement without jamming.
Surely it was developed for use with the waist belay, and then adapted for use with the Italian Hitch. I can't think it was ever the manufacturer's intended method with the Sticht Plate or Tuber, any more than with more modern devices (though I guess someone might come up with evidence to prove me wrong).
