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.
Horseman's pick The horseman's pick was a weapon used by cavalry during the Middle Ages in Europe and Indo-Persia. This was a type of war hammer that had a very long spike on the reverse of the hammer head. Usually, this spike was slightly curved downwards, much like a miner's pickaxe. The term is sometimes used interchangeably with "war hammer". A metal-made horseman's pick called "nadziak" was one of the main weapons of the famous Polish Winged Hussars. A weapon of late make, the horseman's pick was developed by the English and used by their heavy Billmen, a unit of heavy infantry. It was used with great success during the Hundred Years' War. A use of the horseman's pick was to tear men from their mounts.
