The two handed sword was a trademark weapon of the German Landsknecht mercenaries.
These swords represent the final stage in the trend of increasing size that started in the 14th century. The two-handed sword acquired the characteristics of a polearm rather than a sword due to their large size and weight and therefore increased range and striking power. Consequently, it was not carried in a sheath but across the shoulder like a Halberd.
By the second half of the 16th century, these swords had largely ceased to have a practical application but were still seen as a symbol of status. They continued to see ceremonial or representative use well into the 17th century.
