The Swiss Army knife is a pocketknife or multi-tool manufactured by Victorinox (and up to 2005 also by Wenger SA). The term "Swiss Army knife" was coined by American soldiers after World War II due to the difficulty they had in pronouncing "Offiziersmesser", the German name (lit. "officer’s knife").

The Swiss Army knife generally has a main spear point blade, as well as various tools, such as screwdrivers, a can opener, and many others. These attachments are stowed inside the handle of the knife through a pivot point mechanism. While the handle of the Swiss Army Knife is usually depicted in its traditional red color, other colors, textures, and shapes have appeared since 2006. Also since 2006, the handle of the Swiss Army Knife bears a Victorinox or Wenger "cross" logo or, for Swiss military issue knives, the coat of arms of Switzerland.
