The Victorinox US Navy Classic SD Swiss Army knife is a small, keychain-sized Swiss Army knife sold primarily on US Naval bases. It has the US Navy seal, instead of the usual Swiss insignia. Although the US Navy is relatively large, this is the least common of the US military Classic knives.
There are no similar knives from Leatherman or Wenger.
