Victorinox has created a version of the classic Swiss Army Knife that has a USB key as one of it's tools. This, for those that don't know about USB devices - like my parents, would allow you to connect your knife to your computer and transfer data to and from your knife. So if you're thinking about burning your favorite MP3's to CD to take to a friends house, with this invention all you would need to do is download the files onto your knife and then plug it in to your pals computer. I already carry my knife with me everywhere anyway; this would be way more useful than say a corkscrew or nail file.
