On the opposite end of the spectrum from Victorinox’s massive Swiss Champ XXL are their nifty Mini Tools:
The cleverly-designed tools tuck away in the corkscrew of your Swiss Army Knife, giving you the ability to work on tiny stuff: The set of 4 includes a mini flathead screwdriver for repairing eyeglasses or sunglasses, a T4 Torx, a Philips 000 and a SIM card pin.
The only bummer is that you can only stow one at a time.
