The indian Katar is a punching dagger , as such, the design itself is unique. It is an ancient hindu weapon that was later adopted by the muslims.
Usually made of an all-steel construction, the hilt commonly consists of a pair of handle bars that are right angles to the sides which extend upwards parrallel with the users arm. The triagular-shaped blade is normally cut with a number of fullers, although in the 16th and 17th centuries it became fashionable to fit Katars with European blades which have parallel sides to begin with.
Because the katar's blade is in line with the user's arm, the basic attack is a direct thrust identical to a punch, although it could also be used for slashing. This design allows the fighter to put their whole weight into a thrust. Typical targets include the head and upper body, similar to boxing. The sides of the handle could be used for blocking but it otherwise has little defensive capability. As such, the wielder must be agile enough to dodge the opponent's attacks and strike quickly, made possible because of the weapon's light weight and small size. Indian martial arts in general make extensive use of agility and acrobatic maneuvers. As far back as the 16th century, there was at least one fighting style which focused on fighting with a pair of katar, one in each hand
