I had a torx handle with a single screw driver bit attached, left over in my backpack. (So basically just a screwdriver)

Combined, it barely exceeded the maximum safety length. If I'd stored it separated, it would have been fine.

I offered to separate it, that wasn't going to work. I needed to leave one of them behind. ...as the rest of the socket set (at home) needed the torx handle, I left them with the screw driver bit.
