The sai (釵) is a weapon found prominently in Okinawa (there is evidence of similar weapons in India, China and Indonesia). Sai are often believed to have originated as an agricultural tool used to measure stalks, plow fields, or to hold cart wheels in place, though the evidence for this is limited. Its basic form is that of an unsharpened dagger, with two long, unsharpened projections (tsuba) attached to the handle. Sai are constructed in a variety of forms. Some are smooth, while others have an octagonal middle prong. The tsuba are traditionally symmetrical, however, the Manji design developed by Taira Shinken employs oppositely facing tsuba.

The sai's utility as a weapon is reflected in its distinctive shape. With skill, it can be used effectively against a long sword by trapping the sword's blade in the sai's tsuba. It has been alleged that skilled users were able to snap a caught blade with a twist of the hand. There are several different ways of wielding the sai in the hands, which give it the versatility to be used both lethally and non-lethally.

Traditionally, sai were carried in threes, two at the side, as primary weapons, and a third tucked behind, in case one was disarmed. As a thrown weapon, the sai have a lethal range of about 20-30 feet. Throwing the sai was typically used against an opponent with a sword, bo or other long range weapon. The heavy iron (or in contemporary versions, steel) sai concentrate enough force to punch through armor.

The jitte is the one-pronged Japanese equivalent to the (Okinawan) sai, and was used predominantly by the Japanese police during the Edo period. It is a featured weapon in the curriculum of several Japanese Jujutsu and koryu schools.

Popular culture

Sai have been featured in popular culture as well. However, portrayal in popular media generally has little to do with the history or traditional uses of sai. In particular, popular media often incorrectly portray the sai as having an edged or pointed blade, as if it were a dagger or stiletto. Also, they are often popularly portrayed as being the weapons of ninjas, which contradicts their history as the weapons of law enforcers. Sai practitioners have included:
