Seen in the movie ELEKTRA. Has a central, rounded or octagonal shaped steel blade and can be between 15-19" in length. On either side there are two smaller prongs used as wrist guards. The sai can be used for a number of things such as stabbing, slashing, punching, blocking, and throwing. Very useful against swords. Mainly used in pairs.
"Dude, you flippin destroyed that guy and his sword with your sais!"
"I can also fight off multiple enemies with them too."
"Yea, you kicked his butt! Can I look at them?"
"Get your own, I bought these for only $50.00 at century!"

Sai is a boy with a BIG OLE mouth!! Man, nothing can get that boy to SHUT UP!!

I could kill him, but he would go on and on about how his stab wound HURTS!! I promise if I did not have morals, HE WOULD BE DEAD. He is 2’2, but in class he shouted,” IM TALL”
Sai: you don’t tell me to shutup
