Sai Guy

The sai was originally an agricultural tool, but then became an Improvised Weapon often associated with Ninja.

In real life, sai are very rarely actually bladed weapons, and are primarily used in defense in order to disarm and/or break blades. In fiction, however, the middle prong (or both) is usually sharpened into a makeshift dagger. (Sometimes Truth in Television, but not normal practice.) Unusually, Dual Wielding a pair of sais is Truth in Television.

The Other Wiki has more details on the historical use of the sai [[http://en.wikipedia.org/wiki/Sai_

This is not about some sort of Rhino Man, or characters whose name is "Sai".

 * One of the preferred weapons of Zaran the Weapons Master in the Marvel Universe.
 * Teenage Mutant Ninja Turtles: Raphael's Weapon of Choice

Film

 * The Mummy Returns: a Flash Back has a duel between two women Dual Wielding these, which doesn't make sense as sais originated from Asia, not Egypt. And more specifically, sai were a rice-agricultural implement, and the Nile has always been primarily wheat territory.
 * The Matrix Reloaded: Neo used his powers to pull two sais off the wall and fight with them during his battle with the Merovingian's minions. He ends up using them to pin one of his assailants to the wall.

Live Action TV

 * Xena: Warrior Princess's sidekick Gabrielle makes a point of fighting principally with a pair of Sai, starting in Season 5 and lasting until the end of the show. The exclusivity of the weapon to Gabrielle made them all the more cool.
 * Deadliest Warrior: the Yakuza used Sais as a weapon.
 * Mele / Camille.

 * Used by Vetkin in Battle Realms.
 * Mileena from the Mortal Kombat series fights using a pair of sai.
