Zweihänder

Weapon/Tool purpose & use
The Zweihänder is a large sword that is unwieldy to normal people. Thus it is more conventional as a polearm than an actual sword for those who are not skilled as fighters. Those who do however are able to wield this monster-sized sword to decimate droves of foes in some fell swoops.

Weapon/Tool History
This is a sword that was often used by Landscknecht, hired mercernaries, within late medieval times. They were used to and against pike formations, those properly trained in using a Zweihänder being capable of quickly breaking said pikes or spears.
