Dacian Falx

[Brennus]

There's also the chance that these weapons would be very effective when using them against the indigenous armies, but less so against more heavily armored and disciplined Legions. Just a thought.

Very good point! Now, I'm no expert on these peoples, but if they were a tribal society than perhaps some of these weapons were first used in skirmishes amongst indeginous peoples (and proven effective) and were thus carried over into battles with the Romans. For example, Some Celtic weapons seemed more suitable for one on one combat, something that was more suitable to their tradition of warfare (small tribal skirmishes, individual challenges, etc. etc). "Some" of these weapons (there was a great variety of designs) may not have proven as effective against the Roman method of warfare as they would have against other tribes. Could the same be said of these Dacian weapons? While the falx appears to have been at least somewhat effective against the Romans, perhaps it was more successful against indigenous armies, as Demetrius suggested.
