Swiss Army knives are widely used outside the army. They are multi-functional tools, and many sizes and functional combinations are produced. NASA astronauts have a Victorinox knife as standard equipment.[5] Victorinox knives have also been taken to Mt. Everest and the Arctic. The "Champion", Victorinox's model flagship prior to the introduction of the "SwissChamp" in 1986, is in the New York Museum of Modern Art's Permanent Design Collection.
