He says Europe, but only cites one example from the UK. (No surprise there, then - they are the very most restrictive.)

I EDC a fixed blade, which can be up to 12 cm in blade length (just shy of 5”) - currently the very nice and useful Bark River Mini Kephart (look it up). I used to EDC one of my Chris Reeve Sebenza folders, but the local stupid law does not allow one-hand opening knives to be carried in public. Locking folding knives are OK, as long as the require two-handed opening. Larger knives are also allowed if there is a “valid reason” to have them in public...camping, pick-nicking, bushcraft, etc.
You can legally own any kind of edged weapon though, even switchblades or swords. Just keep them at home.
When in the course of human events....
