I'd pull an Indiana Jones against either of those!I thought this demonstration was fun and amusing:
Sword Fighting (Krabi Krabong) Demonstration - YouTube
I have an older (25 years?) hand-forged Thai sword like that with about a 20" blade. But mine is sharp and quite heavy. It would take a strong man to wield one properly, not like these thin things.
Sword fighting against even a remotely evenly matched opponent would be terrifying. But in the times they were the primary weapon, you had no choice. Overall, I think a good sword is the best hand to hand weapon around, although others have their advantages, such as a good spear or polearm if fighting in an open area.
