Looks like one of the older blade designs of all time...The Old Trick or TOT
... but then we'd need a shorter blade whose name spelled TATER to accompany it...
Too bad "War Dog" is taken. How about:"War Dog Maximus
Since there's a Gladius, why not make this the Xiphos
The Xiphos was the Greek short sword used by the Spartans
Looks a LOT like this awesome blade!
Or the Scraphos
The Brotherhood of Xiphos Cutter
