The campers favourite has evolved. As well as containing a blade, bottle opener, scissors, and screwdriver it now features a detachable MP3 player and a computer connection. The state-of-the-art knife can store and play up to 250 songs downloaded from the internet. And with a built-in USB connection and memory chip which stores the same amount of data as 50 floppy disks, campers can use it with a laptop in their tent.
