MadMark, I have been very much involved in the design of a
Gladius Hispaniensis, the first of the line of
gladii used by the Roman legions, and have made a considerable study of the forms and varieties of Roman swords, both
gladii and
spathae from the period of the adoption of the
Gladius Hispaniensis during the Second Punic War through to the collapse of the Empire in the West in 476 CE as well as the successors to these swords used during the following Era of Migrations. The bottom line is that you do NOT want to get me going on that "Gladiator" sword. It may be well made and it is certainly less expensive than buying one from Eric Stevenson at Phoenix or from Albion, I have to wonder at the weight, since he doesn't care to enlighten us, and about the scabbard. I can see that the sword bears no resemblance to any
gladius ever found or seen depicted in any representation, so i have my doubts about the accuracy of the scabbard. On the whole, I should avoid it if I were you.
I am editing this post to say that the design of the
Gladius Hispaniensis to which I refer was done for Eric Stevenson of Phoenix Metalcreations at
http://www.phoenixmetalcreations.com/, with his help and the absolutely essential assistance of Michael Bishop, co-author of
Roman Military Equipment From the Punic Wars to the Fall of the Empire, and of Matthew Amt, Quintus Darius Macro, Optio of Legio XX, and recognized expert in Roman military gear.
If you want to look into an inexpensive
gladius try the newer Deepeeka line that were woked up in conjunction with Dan Peterson. For a bit more money, try Kris Cutlery at
