I'm afraid I have to respectfully disagree with your conclusion regarding the sword's effectiveness. These are front-weighted swords; that is the diamond shaped wider tip with a narrower shape of the rest of the blade. This would give the user a stronger slice, especially on a downward chop, acting more like an axe against armor, as well as against a thinner sword used to try and parry the attack. Thus, they would at least hold their own against other sword-types, and would be more effective against armor.
