Hidden Secrets - New "Hollow" Dagger?

[River]

So when I was watching the Hidden Secrets trailer, I was very curious as to what sword the captain of the War Frigate was using.
I paused the video at 0:26 and saw what appears to be a new dagger/sword of some sort:

I just so happened to find this sword/dagger familiar.
So I did a little research and it turns out that @John Foulroberts made a post about some unreleased weapons a few years ago
(link to his post: https://piratesforums.co/threads/unreleased-weapon-models.6401/)
The sword/dagger you see in the screenshot looks EXACTLY like one of the unreleased daggers he went on to talk about. Here is the unreleased "Hollow" Dagger image:

[Peter Goldbeard]

Cool! I hope they add some new weapons after the full release, and this one sounds pretty cool!

 

[William Foulbutler]

Ooh nice find indeed! Can't wait to see how/if this is used.

 

[Divine]

Seems deadly. the pirate seems to have cut his own hand off, and is still managing to wield the blade!

Edit; just saw hand rofl, still nice catch

 

[Mocha Joe]

Nice detective work.

 

[Miles]

Excellent work finding that. It looks like an awesome model, I wonder what they will do with it in the future.

I saw that dagger and wondered as much!

That's a dagger!?
It's bloody massive!
It may as well be a machete!

Actually in real life, Hollow Daggers tend to be pretty long.
