Thanks for your reply, Laserowy.
It seems clear there are no hilts in the PC version, I've played it through 1.5 times now. In a way it makes more sense, the Apprentice should have his own homemade saber, it adds to the character. It's not too shabby a design either, kind of a cross between Anakin's and Obi-Wan's. It's nice when he field-strips it using the Force in one cutscene.
