I noticed that if you shred just the edges of a thick group of paper, it will get stuck, and only shred about 3/8 inch.
I proceeded to reverse it and looked at the papers.
They were firmly interlaced, with the shredded parts facing opposite directions. I tried to pull the papers apart to shred
them, but they resisted quite well.
It was about as strong, or maybe even stronger, than a staple.
This alone would make an extremely useful way to group temporary document without the use of staples.
We could carry it further for more permanent documents by bending and taping the interlaced, semi-shredded edges sticking out.
I have tried it and found that it works very well as far as binding goes.
An easy way to file documents that need to be grouped together without folders.
