The one in the glove box is totally legal, blade 3" or less and not locking.
But I could put tothern in the locker in the back. When trqavelling I have an enormous quantity of tools in there. So if they wanted to do me for anything they could do me for the jack handle, screwdrivers, breaker bar....
But I think they would have to prove that it was going to be used for a nefarious purpose.
and to get to those tools I would have to move luggage in the back, plus the two planks I use to make a shelf which rest on top of the lockers.
The only other thing to do would be to take the Leatherman-lookalike apart and remove the two locking blades.
Or file off the locking tabs.
