Help me identify 'Iron Knot'. A 'self releasing knot'.

I hope someone here can help me with instructions for a knot. A few years ago, a guy showed me what he called an 'Iron Knot'. It will hold any weight, even up to the breaking point of the rope, but when the tension is released the knot comes apart. Useful for lowering buckets off a roof for example. When the bucket lands on the ground, the knot falls open and you can pull the rope back up.It was practical and elegantly simple. And I forgot how to make it before I made notes. I'd be grateful for any help so I can stop kicking myself.Best, and thanks,DB.

Hello fellow knotheads. I'm still looking for the elusive Iron Knot.

Best, and thanks,

Yes, it's an old thread, but with an unanswered question, still.

It would help to post this to the IGKT's forum at
www.igkt.net/sm, under Practical Knots.

And it would help to have some details on :
1) what rope you've tried this knot in (or in which
you saw it tied & used) --or did you even do this,
or otherwise only get some tying instruction but
never actual-factual usage?

2) how quickly/simply tied it was (just to try to better
understand what might be its brevity of structure);

3) how many strands of rope ran through the hypothetical
bucket handle --just one, or a bight (pair) ?!

These clues might guide some imagination towards re-discovering
the mysterious-so-far "Iron knot". --or something else as effective.

Cheers,

I climb coconut trees and we wonder how to tie a knot we can then loosen ourselves....

alas after failing trying to reinvent the wheel, we tried tying a simple Single Sheet Bend with 1/2" climbing rope under tension (full rack of coconuts about 180lb), and was all we ever needed! Make sure to have as short of a tail end as will hold the knot.

For buckets: 550 paracord and Voila!

It took playing around with rope types/widths to find which one works best for each application. It's not "The Iron Knot" but it works.
