rapiers are always useful, though I don't know if they make ones that are actually sharp. Probably something along the line of an estoc but longer, plus some knives for extreme close range.
May I recommend the Italian Schiavona. It has the aesthetic of a rapier and the practicality of a bonified war-sword. Slices, cuts, and thrusts.
I mostly prefer Bastard swords but pistols are cool because they're light weight and easy to hid. Revolvers most of all, if my avatar wasn't obvious enough.
