十手

The mastery of Jitte 十手 ("Ten Hands") should in theory enable one to face ten adversaries. Some claim that the name is derived from the position of the raised fists, resembling a type of sai known as a jitte, which occurs a number of times in the kata. This rather short kata of only 24 movements contains a number of defenses that can be implemented against the bo.

Both "Jitte" and "Jutte" are correct pronunciations and romanized spellings of the kanji 十手.
