Cuff-fu

Lexicon Entry
Within the Ikusa school of arrest techniques is "cuff-fu," a peculiar art that involves fighting with handcuffs.

It is characterized by using cuffs like brass knuckles to bolster both offense and defense, and specializes in immobilizing an opponent's limbs, a general focus of the Ikusa school. Since handcuffs can easily be concealed in one's pocket, the art has proven quite popular among those who are less aggressively inclined, such as Wato.

However, unlike other weapons, nothing in daily life resembles the shape of handcuffs, making any on-the-fly improvisation difficult.
