I would imagine it's just a different sword. She's a skilled swordsman, she was only using that specific sword to defeat Ares. She had ~70 years to get another sword between movies

Edit: I was thinking WWII. She actually had close to 100 years to get a new sword

Yep, different swords.

Thanks, guys. Yeah, a friend of mine explained that to me after I posted, I just hadn't gotten a chance to get back on here. Even though I'm a die-hard Lynda Carter fan (and the series will always be tops in my generation/age group for the most part), I just don't see why Diana can't do everything with her bracelets and lasso. The shield and sword make her too much like Xena to me. The whole point of being a "Wonder" woman should be that she doesn't need the sword and shield. Lynda blocked MACHINE GUN bullets with only her bracelets in the pilot movie (1975). Just my opinion. Ho hum.
