Wenger is a company that creates the types of knives that were first used after what period?
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.
Neck knife A neck knife is a knife worn on a cord hanging from a person's neck. It usually means a small fixed-blade knife which is carried by means of a cord, by which the knife sheath is suspended from around one's neck. They can either hang handle up ("mountain man style") or handle down. The knife may be hung from a loop of natural or synthetic cord, a length of braided paracord, a leather thong, or even a breakaway beaded or ball chain such as those utilized for military dog tags.
