Ikkaku-ryū juttejutsu (一角流十手術) is a school of juttejutsu (or jittejutsu) that, as the equivalent to its sister variant Chūwa-ryū tankenjutsu (中和流短剣術), is taught alongside traditional school (koryu) of Japanese martial arts, Shintō Musō-ryū. It is composed of 24 forms (kata) divided into two series. It was created by the third Shintō Musō-ryū (SMR) Headmaster, Matsuzaki Kinu'emon Tsunekatsu in the late 17th century.

Ikkaku-ryū juttejutsu utilizes the jutte as a way of self-defense for use against an attacker armed with a sword (katana).

The original tradition of Ikkaku-ryū did not specialize in the jutte, but was a system of seizing/capturing arts (toritejutsu) with the jutte being one of several weapons and skills used. These weapons and arts included the war-fan (tessen), grappling (jujutsu), short-stick (tebō) and short-sword (kodachi). Originally the complete Ikkaku-ryū was taught in the New Just (Shintō) Musō-ryū branch and the Ten'ami-ryū as an arresting/seizing-system for the local security force of the Kuroda domain. After the Meiji-restoration the two largest surviving branches of the Kuroda-no-jo tradition,Jigyo and Haruyoshi -branches of New Just (Shintō) Musō-ryū, was merged and streamlined into what would become the modern day Way of the Gods (Shintō) Musō-ryū system led by Shiraishi Hanjiro. Of the original seizing-arts of the Ikkaku-ryū only the jutte and tessen arts was incorporated into the new system.

The (jutte) is a baton made of iron with a small tine or prong fitted just above the handle. The gripspace of the handle is wrapped with a cord that hangs down from underneath the handle with a tassle at the end. The jutte was mainly used by police-forces of the Edo-period of Japan and is known to have had over 200 variations.

Ikkaku-ryū fields a truncheon about 45 cm in length with a weight of about 550 grams. It has a smooth shaft ending in a handle wrapped in a coloured cord ending with a hanging tassel. A small tine is attached just above the grip. Originally the colour of the wrapping-cord indicated the social level of the wielder. The original design of the Ikkaku-ryū jutte had a hexagonal shaft cross-section with the tine attached to one of the corners instead of the flat surface. The inside of the tine was also sharpened which enabled the wielder to use it for cutting if applicable.
