The default lighting on Sketchfab doesn't show the details well. I recommend changing the rendering option to "Matcap" to highlight the surface details. And, of course, you can download the model for yourself if you like.
The idea that these are ancient Roman swords is just a joke. There is zero positive evidence for that idea and a heap of accumulated evidence against it. I've placed an open invitation on the Fake Hercules Sword group on Facebook if anyone (including Hutton Pulitzer) would like to come on and tell us why any/all of these Fake Hercules Swords are or are not ancient Roman artifacts.
Remember when Pulitzer said the actual Italian eBay sword was "fake, cast iron, and whatever"?
Remember when Pulitzer said the photo of the Italian eBay sword was of an "original" sword that was in the Naples Museum? His followers continue to spout that nonsense to confuse the issue. The sword mailed to New Brunswick was the same one shown in the image on eBay. Any person with two eyes can see that.
Remember when Pulitzer said the Oak Island sword had gold on it? It doesn't. It never did. He was looking at brass exposed by the fake patina being worn away.
Remember when Pulitzer said that Christa Brosseau's high zinc results were wrong and that he would release his own XRF data showing little to no zinc? But that release of data never happened. Instead, he produced a 3 GB "report" trying to explain why Brosseau's results were consistent with ancient Roman brass.
And what about that original in the Naples Museum?
And what about the "legend" talking about ten swords being made?
And what about the "magical powers"?
Who still believes this story about a "Roman sword from Nova Scotia"? And why? That's a serious question.
