Traditionally, a zanbatō (斬馬刀) is an especially large, curved type of fictional sword used by characters in Japanese anime and manga. Books written about nihonto (traditional Japanese swords) make no references to zanbatō as being actual swords used in feudal Japan. The name zanbatō literally translates to "horse-slaying sword" or "horse-chopping saber". Replicas of zanbatō swords can be found for sale in tourist shops and stands in Japan. Extremely long zanbatō type swords existed in Japan as in the nodachi or ōdachi; these swords, along with the phonetically similar zhan ma dao Chinese sword, may have been the inspiration for the creation of zanbatō as an anime and manga weapon.
In Shinobido Edit
Kabuto is often seen with a zanbato in cutscenes and battles, but very rarely uses it; when he does is as a projectile (usually at the beginning of the battle) and doesn't bother to pick it up again for the rest of the fight. It also defies general convention somewhat by being a rectangular slab of metal sharpened on one side instead of a curved or dual-edged blade.
