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.
Ahlspiess The Ahlspiess (or awl pike) was a thrusting spear developed and used primarily in Germany and Austria from the 15th to 16th centuries. The ahlspiess consisted of a long thin spike of square cross section measuring up to about a metre (39 inches) in length, mounted to a round wooden shaft and sometimes secured with a pair of extending from the socket. The length of the shaft ranged from 1.6 to 1.8 m. (5 - 6 feet), and located at the base of the spike was a rondel guard (a circular metal plate) to protect the hands. Large numbers of these weapons have survived and are kept in the arsenal and museums of Vienna as well as the Metropolitan Museum of Art.
