A jitte (十手, "ten hands") is a specialized weapon that was used by police in Edo period Japan. It is also spelled jutte.
In Edo period Japan the jitte was a substitute for a badge and represented someone on official business and was carried by all levels of police officers including high-ranking samurai police officials and low-rank samurai law enforcement officers (called okappiki or doshin). Other high-ranking samurai officials carried a jitte as a badge of office, including hotel, rice and grain inspectors (aratame). The jitte is the subject of the Japanese martial art of jittejutsu.
In feudal Japan, it was a crime punishable by death to bring a sword into the shogun's palace. This law applied to almost everyone, including the palace guards. Due to this prohibition, several kinds of non-sword, defensive weapons were carried by palace guards. The jitte proved particularly effective and evolved to become the symbol of a palace guard's exalted position.
In Gameplay Edit
It's the weapon of choice of the Kenobi Ninja. The Kenobi use a sharpened version, something of an hybridization of jitte and ninjato, and is funcionally identical to the ninjato used by the protagonists.
