I know this is an old thread but another modern take on the Gladius is done by a guy named John Gage. He calls his the "tactical gladius". His modern style is useful in that it has a full tang handle rather than a cylinder or push tang like the ancients. He can also do different finishes on the blade including satin, matte black and camoflauge. I own one with a satin finish and love it. You can check him out here: http://gagecustomknives.com
