I note from readtiger.com an interesting weapon description
Quote"Daggers and knives.
These were of various shapes and kinds, each with a separate name.
Name Description
Katara or Katari A lightweight thrusting knife similar to a poignard and peculiar to India. Made with a hilt whose two branches extended along the arm so as to protect the hand and part of the arm, this weapon had a thick blade with two cutting edges having a breadth of 3 inches (76 mm) at the hilt and a solid point 1 inch (25 mm) wide. The blade could not be bent and was so stiff that nothing but a cuirass could stop it. The hilt had a cross-bar at right angles to the blade, by which the weapon was grasped such that it could only be used for a forward thrust. Some were slightly curved whilst others resembled a fork or were two-bladed. Blades were of various patterns with a length that varied from 9 to 17.5 inches (230 to 440 mm). Push dagger Deccan and Hindustan
Jamadhar This had the same handle as a katara but with a broad and straight blade, while the katara blade could be either straight or curved. The jamadhar katari had a straight blade and a handle held in the same way as a table-knife or sword".Unquote.
