I can't tell if you're working from an original concept, or an actual weapon, perhaps something like this: The hilt seems too short, and the blade too narrow. Some of the details can probably be removed from the diffuse map, relying upon the specular map to show them.
Only thing I could add on is that the grip -could- be simplified by a baked normal map as opposed to protruding edges. And the blade's normal map is far too rough: only deep scratches should (IMO) be visible, otherwise don't really bother with the diffuse noise-baked maps.
