Definitely AP, as Odaswifteye mentioned. If you build AD, you're forsaking a potential combined AP ratio of 1.0 from Bouncing Blade and Shunpo, which sorta leaves you with two somewhat-useless abilities if you capitalise on attack damange.

Funnily enough, I remember Rageblade being quite a popular item on Katarina when I first played it, but I definitely wouldn't recommend it now. Hextech Gunblade is still an incredibly viable item, so if it fits your playstyle and preferred build, absolutely go ahead with it. I personally don't build it but have no qualms with it, considering it adds a tremendous chunk of damage.
