I have a super Victorinox (6 blades, one mini saw, two screwdrivers and a corkscrew) gizzit from Pilatus. They gave it to me after I lent them a paddle when they were up **** creek, but Pilatus aren't an airline of course.
I also had a tiny Boeing Logo Victorinox mini knife gizzit with one small blade and a nail file, but Changi security confiscated it. I snapped the blade off it before dropping it in their collecting box - if I can't keep it, no-one else can.
I hate Changi security - they're so damned petty. They even tried confiscating my hair cream 'cos it was 25 ccs over size, but they only got the tube.
