While accounts of the ninjas have achieved mythic proportions, the fact remains that they were fearsome warriors of their age. Like all warrior clans, ninjas also have their own weapons. However, it is a misconception to believe that certain weapons were used by the ninjas exclusively. More importantly, the choice of weapons used by the shinobi depended greatly on their work.

Ninjas were mainly employed as spies and arsonists. This meant that they had to go about their work in secret. They could not use any weapons which could expose them. For the same reason, they did not have any unique weapons. If caught, the presence of those weapons would have instantly revealed the shinobi for who they were. Therefore, the ninjas used weapons which were commonly used in their age. Alternatively, they used weapons which could be used in some other non-lethal capacity such as the staff.
