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.
Anglo-Saxon warfare The period of Anglo-Saxon Warfare spans the 5th Century AD to the 11th in England. Its technology and tactics resemble those of other European cultural areas of the Early Middle Ages, although the Anglo-Saxons, unlike the Continental Germanic tribes such as the Franks and the Goths, do not appear to have regularly fought on horseback.
