Sorry for going off-topic. My fascination with the
mamluks got the better of me

.
I have to admit I also know hardly anything about Katars so I didn't feel qualified to comment on that part of the the discussion. I think one would have to go to descriptions of battles fought in the Mughul era and Indian equivalents of the Mamluk
Furuseya manuals to get more info. I must concur with Jim that to me personally the katar has never really "felt" like a military weapon. It has struck me more as a weapon to be used in streetfights, self-defense and by assasins. In battle I personally can only envision it as a secondary weapon. I would imagine the main hand-to-hand weapons used on the battlefield would have been the lance, axe, mace and Tulwar. The longer reach of these weapons would have made a man armed only with a katar very vulnerable. But like I said, what do I know

.
The only real way to test it would be to stab a mannequin wearing an antique Indian mail shirt and gambeson with a katar. Frankly that would be absolutely criminal and the worst sort of vandalism!
