These USB flash drives from Victorinox Swiss Army look cool without knives. These models were announced at CES earlier this year and today both models are shipping. They are waterproof and shock-resistant, and also offer USB data encryption. The Slim and Slim Duo come in sizes of 4GB to 128GB and cost between $39.99 to $349.99 (USD) at the Swiss Knife Shop, Amazon. The Slim Duo basically offers two thin USB drives in the same compact form.
