Indian Mace

[Emanuel]

With regards to the flanged maces, while I agree that they focus the force of the impacts into a smaller point of contact, the fancy spiral ones have very thin flanges. They may be sharpened to an edge, but they are flimsy, therefore not at all suited against armour or anything but the softest targets.

Thick un-sharpened flanges are more effective than, thin sharp ones.
