There are notebooks, writing pads or training materials that have a spiral binding on the edge. This is usually a relatively stable wire that holds the individual sheets together through a very specific geometric deformation. The special thing about it is that this binding is really very stable. So even if one element of the spiral binding were to break off or be deformed, this would have little or no effect on the overall cohesion of the individual sheets. Of course, it is correspondingly tedious if you want to detach the sheets from this binding. This binding reminds me of the property of stubbornness: the wire is close-fitting and quasi far over-redundant shaped like a stubborn arrangement that does not want to allow the cohesion to be loosened under any circumstances. Therefore: stubbornness creates cohesion or holds together. A good quality - as an antipole, when stubborn people tend to annoy you.
I wish you an extraordinary day!
