The Ninjatou (忍者刀), also known as ninjaken (忍者剣) or shinobigatana (忍刀), is the most common name for the [[katana|Japanese sword]] that the [[ninja]] were thought to have carried.  It is often depicted as being a [[short sword]], often portrayed as having a straight blade with a square tsuba.  There is no historical evidence of the 'ninjatou', and modern depictions of the sword originate from portrayals that were seen in early Hollywood movies.
