has anyone used or heard of anyone using this fabric?

I can't find any information on utility compared to Kevlar.
More importantly how many layers to make level I, II, III or how to cut or sew the layers together.
I am mostly just curious, but it might be good information and once I get some spare cash, I want to again pursue my chest plate designs.

Try
here.
There's also this
video from that site.
(Warning: annoying music intro.)
I'm less than impressed based on that performance, but I think it's a carrier design fail. Ballistic nylon/Kevlar would have done much better at keeping the thing from blowing up like a balloon than making the cover out of some cheap pillowcase crap, and the weight penalty would have been negligible.
If a foot square panel will stop multiple .44Mag hits at 1#, other than bulk, one wonders why they wouldn't make a vest out of three such layers, but after seeing the performance, it's probably that if you took two consecutive rounds of weapons fire, you'd look like the Michelin Man, and instead of shooting you, they'd just run up to you once you were stuck in a doorway after the first two or three hits, and slit your throat while you were thrashing around trying to get through.

I wonder if it might be a product which could stop both knives and bullets…
Or, at least, work w. an anti-stab layer on top...

I saw those. I will look again, but I didn't see where they said how many layers the pack has. I am considering using this material in my chest plates, but am not going to spend $100 on shenanigans. Especially now while I am unemployed.

I'm a big fan of body armor, I've been wearing it for almost 20 years and anything they can do to lighten it, and make it more comfortable is wonderful.
What most people forget about body armor is that it is only able to stop penetration, and contain fragmentation. If you're wearing body armor and get shot, you're still taking the hit. If you get hit in the sternum with 600 ft/lbs, you're still getting hit in the chest with 600 ft/lbs. That's going to leave a bruise. It's better than a penetrating wound with much better survivability, but it's going to leave a bruise.

I've heard that if you're wearing armor that will stop a rifle bullet, and you get hit with a rifle bullet, you're still going to be out of the fight for the next hour or so because of the slam your body took. IOW you'll survive, but you won't be doing any fighting in this engagement.

Richard Davis proved that you could take a hit from a full-house .357, and still return fire effectively. As a sidebar, he also introduced us to the wonderful world of bowling pin shoots.
(And the annual Second Chance shoot, in Clear Lake, Michigan, was the most fun you can have, and still keep your clothes on.)

this is just the beginning... we're seeing the earlies days of materials like this being applied.
Here's to hoping there will be lessons learned in how to structure the underlying material, package it, bias it in the package, and so forth. Wouldn't be surprised to see improvements on it. At least I'd love to be on the design/mfg team that tries.
Even as it is today, seems like an appealing choice for applications like backpacks.

I think it's going to be like Aluminum in the 40s and Titanium in the 70s, a somewhat uncommon "supermaterial" that will be used in applications where the economics of cheaper, now existing materials don't force the choice, like boutique applications, extreme performance requirments(like Kevlar and Carbon fiber today), etc. I don't see it getting cheap enough to displace common nylon/polyester mesh, but I'm guessing the transistion to use in production of consumer goods once the engineering/manufacturing issues work out, will be fairly quick - probably less than 5 years for it become an accepted choice for the manufacturer of said goods.

Video evidence from 2005 would seem to indicate that's B.S.
