The only significantly evolutionary part of this that I see is the hinge-wirecutter. If that stands up, especially for chopping, I'd say incorporate it with the Gerber trifold that half of NATO is adopting.
I'm not going to knock it as a shield- it's not much smaller than the small targ sheild some of my friends fence with. I would rather try to block a blade or spikey club with that than my bare hand. But the use as a grapple, uhm, yeah, I'm a full sized computer geek- I don't trust little hinge pins. *blush*
