Katar

Weapon/Tool purpose & use
The katar is a triangular shaped sword. This makes it so the it lines up with the users arm, thus allowing them to use all of their weight into the strike. Though the katar does not have very much defence to it, you can use the flat sides of it to block.

Weapon/Tool History
The Katar, was often worn as a status symbol, this would be worn by Princes, and nobles. The weapon was normally used for self defese but could also be used to show ones wealth. The katar often would have a leaf like or a shell like knuckle-guard to protect the back of the users hand. (Though this was discarded later on, meaning some models may have the knuckle-guard but most do not.)
