I believe that is Blade's sword. Vampire movie with Wesley Snipes. Could be wrong though.
Wrong, that's one of the ones I checked out first. The Daywalker blade is straight and has no hollowed-out parts, as well as having a grip with a bunch of silver rings breaking up the black. It also has a double-edged point, whereas the one posted is a single-edge blade.
My best guess would be something Star Wars-esque, or at least sci-fi in general based on the grip. I thought it might be from Serenity, but the grip on the Operative's Sword is a bit different too.
