Zanbatou
The literal interpretation of the term Zanbatour is "horse-slaying sword." This is the term for a sword used during the japanese feudal era. It was intended to remove a cavalryman's horse from underneath him by "slaying" it in one fell swoop. However, due to its massive size its was determined ineffective in combat and its use was therefore abandoned.
The zanbatou is a formidable weapon.
