 If you liked
Soul Eater

 ...then you might like
Seiken no Blacksmith

Both animes have characters that turn into weapons, while Soul Eater tends to focus more on the fighting and all that Seiken no Blacksmith tends to follow more of the romance part of it while still adding in some good action scenes. So you could think of it like both series are trying to tell certain parts of the same story.
