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...

The "SBARKticus"

Or ’SpartiCUR"

Too bad "War Dog" is taken. How about:
"War Dog Maximus"

Or maybe

"Battle Cur"


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

or

BOX Cutter for short
