Kathi Samu' (sword fight) is an ancient skill, mastered by the royal armies in the northern most coastal Andhra and Karvetinagaram. The swords used for Kathi samu are of various types. Besides the long, curved sword, they also use a Limcha, used in the wars earlier, and Pata, a sword with a wooden cover.
The first among them is the Dal Farri Khadga - a display of two people with swords and shields. Another skill is Gareja: a man holding four swords, two in each hand and move them to protect himself and to strike at the foe.
