Yes - you are right. That line in the video probably wouldn't have made it by our patent lawyer. We are patent pending. Some elements of how our fiber is produced (not in our patent), and some of the R&D things we are trying are trade secret, but for the purposes of simplicity we are patent pending. The fibers are strong but can be cut with a sharp knife or pointy object - anything EMTs or emergency services would have on hand, or something like a seat belt cutter wouldn't have an issue getting through them.

Aw darn. My first thought was protection from knife attacks.

If that worked, you could also sell to that company making the anti-rape pants.

Yea but if you get incapacitated one of the first things they do to get to the wound is cut the clothes around the wound area. If you have pants make of knife proof material your life could be endangered.

Some sports clothing is designed to be resistant to sharp edges [1]. The link is for some ski basewear.

Something thin and flexible won't protect against stabbing very well; the knife will just drive the material into the body. Cut resistant gloves are a thing and usually made of fine metal chain mail, but they're intended for protection from accidents using cutting tools, not assaults. The material used would probably not provide much protection against forceful stabbing.
