Katar

A katar was a punching dagger common to Calimshan.

Etymology
The word for "knife" in Alzhedo is katar, yet when most people used the term "katar", they were referring specifically to the punching dagger used by Calishites.

Description
A katar is a dagger with the handle perpendicular to the length of the triangular blade. It is used for thrusting instead of slashing. It put more force from one's punch behind it, making it capable of deadly attacks.
