I've also seen a glue-less paper binding trick where two pieces of paper are finely crimped together with some high pressure tool in alternating v^v^v^ patterns, actually making tiny tears in the paper. Does anyone know what kind of tool does that?
Kokuyo Stapleless Stapler
In US, you can find it on Amazon for 15-20 bucks.
Possibly this? https://www.youtube.com/watch?v=_NeGah4YJg0
It's a bit hard to search for, because they make one that punches a hole too (shows up in the video).
The problem with these staple-less staplers is that they permanently damage the paper. With a regular staple there are two tiny holes and that's it. You can bend open the staple to get back your individual sheets (e.g. to scan a particular page) and if you want to put them back together you can push the same staple or a fresh one back through the existing holes and bend it close.
You can repeat the process as many times as you want and there won't be any new damage to the paper. With a paperless stapler you would have to do new damage to the paper each time. Also, a regular staple is pretty much forever while these crimped folds can eventually come loose again.
Muji stocked a stapler like this for some time.
