Now that is pretty interesting.

It seems they tuned the material to resist the angle grinder, drill and water jet but it would be interesting to see its ballistic resistance.

I'm not sure why anyone would want cut resistant shoe soles, but I know lots and lots of people who want puncture resistant shoe soles. Isn't that a similar process to ballistics?

I note that they didn't really cover that territory, and wonder if that was lack of facilities or avoiding the tough questions.

Maybe in a sense, but I think not really. Bullet-proof vests aren't necessarily (usually?) stab proof. (And vice-versa of course.)

Wonder what a blow torch or other commonly available chemical agents would do to it.
