I’m not about to test it out but leaving the UK they say you can have a blade up 60mm long in hand luggage. Doesn’t mention anything of the sort when I leave the US though. It’s one of my little fears that I will get to security and I’ve forgotten to put my knife in the suitcase for the hold. Happened once in the us and the guy saw it and deliberately ignored it. I am TSA prechecked so maybe that gave me some leeway.

Knife (with a sharp or pointed blade and/or blade longer than 6cm) No
So it can't be sharp. Or pointed. It's an and/or. Goodness knows how they determine pointyness or sharpness. Maybe get Jacob to help.
Mind you I went through Edinburgh a couple of weeks ago, and they had the scanning machines up that mean you don’t have to remove liquids or laptops. Vastly superior. But not much use if the airport to which you are going (and have to return through) doesn’t do that.
Oh, and the non-Schengen gates process at Brussels airport is woeful - been through there dozens of times, but this was the worst. Unless you have an hour or so to spend in the company of increasingly agitated other passengers I wouldn’t go through there. Train to anywhere else in Europe and fly from there might be better. Memo to self: check whether my Irish or Scandi ancestry can allow me to avoid this farce. And it did me out of my usual relaxed airport lunch. Phew, that feels better.
