Hi Emanuel,
intuitively I believe the outer edge of the sickle would have been mainly used for the 'cut'.
Bravo Fernando....it was there for all to see....if you can decipher Francais...my French is limited to "je voudrais une bière "
I also found that a common tactic during the Madhist uprising involved tribesman hiding/playing dead during the initial Cavalry charge and melee.....and then trying to hamstring the horses on their return .....often using their Kaskara
Regards David
