Dacian Falx

[Ron Andrea]

It may be that the falx evolved as a weapon used against similarly armed and organized (or, disorganized) foes--where it was quite effective--and was used against the Romans because it was the weapon at hand. Lots of weapons and tactics effective in a bar brawl or a one-on-one duel become a liability fighting against a legion in formation or a phalanx, but if it's the best you've got and the Romans have marched into your country, you fight with what's in your hand.
