What Japanese TV anime show had a "reverse blade sword"? I must know. Very important.?

i know your talking about Rurouni Kenshin

Rurouni Kenshin.

rouroni kenshin- kenshin the batousai(manslayer) a wandering samurai after the meiji war carries a reverse blade sword called the sakabato, yes i even remembered the name of his sword.. but it also comes up in the ovas off the series.. samurai x the animation and samurai x reflections( based on kaoru and his married life.. he even has a child kenji!.. and yahiko miyogin inherits the sword later on in his life) a 95 episode series . the reverse blade carried much significance since for his atonement fortakign soo many lives he has sworn never to kill again. kenshin uses a technique called hiten- mitsurugi ryu. he does turn over the blade at various times in the show. but never kills. for his ealry life and why he's called the batousai watch samurai x trust and betrayal( he killed his "wife" tomoe which is why he doesnt kill now)

It depends on if i've watched it with Japanese subs first, if that's it and the voices are not similar to the japanese voice actors. Then I would prefer having subs, but if they sounded somewhere near the japanese voice actors (just speaking english instead) i'd choose it dubbed. You know, when i've just watched a long series of anime in Japanese and im seeing it again in an english dub, without the original voices. Then I feel like there's some other persons speaking, it just feels like that and i'm not much into it. :P You can't change the anime character's souls. Ugliest... meh do I need to answer the bonus question? :D

I believe it was Rurouni Kenshin.

Rurouni Kenshin has one.
