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 on a round wooden shaft and sometimes secured with a pair of langets 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.
