Description and use
Although some sources place the origin of the sasumata in the Muromachi period, most sources discuss its use in the Edo period. In Edo period Japan the samurai were in charge of police operations. Various levels of samurai police with help from non-samurai commoners used many types of non-lethal weapons to capture suspected criminals for trial.
The sasumata (spear fork) together with the tsukubō (push pole) and the sodegarami (sleeve entangler) comprised the torimono sandōgu (three tools/implements of arresting) used by samurai police and security forces. Samurai police in the Edo period used the sasumata along with the sodegarami and tsukubō to restrain and arrest suspected criminals uninjured. The head of the sasumata would be used to catch around the neck, arms, legs, or joints of a suspect and detain him until officers could close in and apprehend him (using hojōjutsu). The sasumata had a long hardwood pole usually around two meters in length with sharp barbs or spines attached to metal strips on one end of the pole to keep the person being captured from grabbing the pole. The opposite end of the sasumata pole would often have a metal cap, or ishizuki like those found on naginata and other pole weapons.
There were also firefighting versions of the instrument known as a chokyakusan, rinkaku, tetsubashira, or tokikama. A similar weapon in China was known as a chang jiao qian, and sometimes called a cha gan or huo cha (fire fork), which had a similar firefighting role. The sasumata type implements were used by firefighters to help dismantle burning buildings, raise ladders, and otherwise assist with their duties.
Today, a modern version of the sasumata is still occasionally used by the police and as a self-defense tool. These modern sasumata are often made of aluminum, without the sharpened blades and spikes found on their medieval counterparts. They have been marketed to schools due to a growing fear of classroom invasions, which has prompted many schools in Japan to keep sasumata available for teachers to protect themselves or students and to detain a potential threat until the authorities can arrive.
