Removable knucklebow ?!?
A very interesting feature Jens; if your example is a hunting sword it would be very good for the final thrust to the animal's heart.
I was poking through the notes and index in Elgood's Hindu Arms and from what I have been able to gather from his notes the swords with the more acute downcurving points are from the Deccan, and that the Kirach was the sword issued to Sikh Artillerymen .
I still am stymied as to why there are so few examples to be seen .
Maybe there just weren't that many Artillerymen .........
