Wenger is one of two companies that have manufactured which pocketknife or multi-tool manufactured by Victorinox AG?
Swiss Army knife The Swiss Army knife is a pocketknife or multi-tool manufactured by Victorinox AG (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.
Multi-tool A multi-tool (or multitool) is any one of a range of portable, versatile hand tools that combines several individual functions in a single unit. The smallest are credit-card or key sized units designed for carrying in a wallet or on a keyring, but others are designed to be carried in a trouser pocket or belt-mounted pouch.
