Interesting. I wouldn't expect hemp would have the tenacity as the fibers we're using. But reading more about it now, it looks like people are trying to do some interesting things with hemp in bulletproof. One challenge might be how fine the fiber can be made. But I'm going to look into it!
> Naturally Advanced Technologies is a company that takes hemp fibers and treats them with a patented enzymatic solution that further enhances their already protective qualities by making the final material softer and thinner than silk, but stronger and lighter. This material, called Crailar, can also be converted into plastic materials similar to the kind Henry Ford’s famous Model T Ford was made of.
