What is "swordstaff"

A Swordstaff (Svärdstav) is a Scandinavian polearm, used in the medieval ages. It is made by placing a blade at the end of a staff.

Evidence of the weapon in use at the Battle of Elfsborg (Alvesborg) 1502 is provided by Paul Dolstein, a landsknecht mercenary who fought in the battle, who refers to the Swedes carrying "good pikes made from swords". He also provides sketches of the weapon. Although Dolstein believed the weapon was made from swords, there is no independent confirmation of this.
