The cure, in gaseous form, and plenty of it.
Failing that I'd prefer a sniper, a shotgun, unlimited amounts of ammo for both, and the rooftop of the tallest incomplete building I can find. Even if the undead think far ahead enough to realize I'm in such a high place, something will distract them by the time they get there. The sniper will be used to kill time, the shotgun to save my ass.
EDIT: I misread, I thought it was what should you have. I do have a cane sword, a machete, a couple long-ass kitchen knives (short swords, basically), and a bunch of things to block my stairway so they can't get at me before some form of army, probably American, comes through guns blazing and saves my ass.
