The jitte is a traditional Japanese weapon used primarily by law enforcement officers during the Edo period. It consists of a metal staff with a small blade at one end and a fork at the other. The jitte was used to block and deflect sword attacks, as well as to trap and control opponents' weapons. It was also useful for applying pressure to pressure points on the human body in arrest situations. Its compact and versatile design made it an essential tool for law enforcement in ancient Japan.
