The Abandonment of the Gladius for the Spatha - Why?

[petrinus]

HA! that is funny....lol, yes close and finsih comes to mind, the enemy sprawled inviting his end, but with good form and the right anfle the cut is not off balance and just as, if not more powerful. the only association i was making between a falx and katana were the fact they share the curved blade and one or two hand variety, the two handed falx im thinking was more like a naginata?, pole arm esque? i dont know. i should like to study up more on the dacians and there weapons, do you think dacian engagements neccessitated the spatha more so or ?
