The Wenger Computer Wiz is a rare, retired, pocket-sized 85mm Swiss Army knife with a built in Torx wrench. It was model #16962. If you are looking for a practical knife for quick technical repairs, consider a CyberTool 29 instead. It has a bit driver with multiple Torx bits, and you can easily swap in more sizes. This knife is a rare collectible that was more cute than practical!
