The trouble is that most Samurai swords aren't really Samurai swords (katana) anymore. Most of what's out there are cheaply made imitations... so brittle you wouldn't survive the first zombie wave. Plus, you'd really need require menkyo in one sort of sword technique or another (nitto ryu, kendo, etc.) to be effective.
