I've finally found a bag which nicely fits almost everything I want to carry every day, and alos makes everything easily accessible - it is about the same size as what I used to carry, but now I no longer need to dump everything out to find what I neede, even with some lose parts still in there.

There's also planet computers - though the cosmo had some reliability issues at least in the early versions. My gemini still works, and I'll eventually get another cosmo. As daily phone the unihertz is more comfortable, but the two communicators allow you to do proper work with touch typing - on a keyboard better than the larger GPD pocket.
It is a Victorinox swiss champ. Only flew twice last year - both times forgot the pocket knife. First time I stuck it in my backpack and hoped they don't notice, which they either didn't, or didn't care. At the destination I realized that I also had my multitool in the backpack.
On the way back I forgot it yet again, and just was trying to put it a bit deep under my jacket - and while waiting to go through saw from some distance two police officers opening the blades, discussing it, and just putting it back.
