73 Armin
The only time I saw it done, we had to lower a rope to a guy who had run out of steam while soloing a route. I looked like useful knowledge so I learned it but never had to use it!
The prusik is often difficult to loosen after it’s been tightened - a far better alternative, which is similar to the prusik, but much easier to loosen, is the Klemheist loop:
I’ve used both when needing to ascend a rope when in difficulty, and it’s hands down the Klemheist for me in such a situation, where one needs to alternately tighten, loosen, shift up, and tighten the knot many times in a row to ascend the rope.
Armin, are you sure we need to hang people for transgressing the Sota rules?
Another inefficient way of tying a knot - Its much easier to simply 'swing or ‘twirl’, the end of the loop around the other rope then push it through the loop.
There are other versions, as you probably know and most of them are better than the standard prussik.
I’ve never had that problem. Pulls right off.
It’s a well-enough known problem that many have sought alternatives over the years which are similarly easy to tie, but which are indeed distinctly easier to loosen. As David mentions, there are several versions.
My go-to knot is velcro. After that I suppose the clove hitch comes in second place. I know a lot of knots, I just generally don’t need them.
Okay, well, to me, that’s a solution in search of a problem, but everybody’s mileage will certainly vary.
Enough half hitches will hold anything.
‘If you can’t tie knots, tie lots’?
I made a video with my favorite knots: https://youtu.be/QM1SYsHXZLA
Nice for tying down airplanes, as well! Followed by some half hitches, of course.
