Manufacturers
The Swiss company Victorinox AG and up to 2008 its wholly owned subsidiary Wenger SA supply about 50,000 knives to the Military of Switzerland each year, and manufacture many more for export, mostly to the United States. Many commercial Victorinox and Wenger Swiss Army knives can be immediately distinguished by the "cross logos" depicted on their grip shells; the Victorinox cross is surrounded by a shield with bilateral symmetry, while the Wenger cross is surrounded by a slightly rounded square with quadrilateral symmetry. Since 1961 the military issue knives supplied to the Swiss Armed Forces bear the Swiss Coat of Arms.
Many other companies manufacture similar-looking multi-tool folding knives in a wide range of quality and prices. The color red for multi-function knives, the cross-and-shield emblem, and the words SWISS ARMY are registered trademarks of Victorinox AG and its related companies.
