Badass knives come in all shapes, sizes, and designs. But the latest Badass Knife of the Week is like no other knife that came before it—well, maybe not for a couple thousand years at least.

The US Gladius Thraex XII is a unique knife that’s based off the design of the Roman Gladius sword from 19 centuries ago.

Although we’ve written about this knife quite a bit, it hasn’t been named one of badass knives yet. Here’s what we’ve said about it in the past:

Put out by US Gladius—a brand that bases its designs off ancient swords from Roman times—the Thraex XII Tactical takes some of the important design cues from the Roman Gladius to offer a new and distinct look unlike anything else.

The Thraex XII Tactical is a functional tactical knife with an 8-inch blade made from black titanium-coated 8Cr13MoV with a full tang and Micarta scales for the handle. It weighs a solid 11.1 ounces and boasts an overall length of 12 inches.

Even though the original Gladius swords were meant mainly for piercing and stabbing, the double-edged blade (which includes a serrated edge) makes the Thraex XII more versatile.

But the real throwback piece of the knife is its rounded pommel. The original was used more ornately, but the pommel on the Thraex XII serves to give the knife balance, prevent it from slipping out of your hand, and provide a striking mechanism.
