I would have to grind down the blade on my PS4 by a little more than a 1/4" (6 mm) to make it work.
A PS4 shouldn't be a problem at all. Same with a Micra or Style CS.
I measure my PS4's blade as 5cm including pivot, and its length closed is under 6cm.
I suspect small pocket tools like this are the reason for the change in regs. Searching for these wastes a lot of time in the security line without increasing public safety in any meaningful way.
However, while a PS4 is handy around town, it's severely limited in off-pavement use.
