This knife doesn't look very threatening at all, it's probably used to cut ropes or open boxes. I like the way you can flip the blade in and out with the switch on the handle though. It has a very basic design to it.
I found this to be very interesting. In that the blade is enforced with carbon fiber. Ideally making the knife as a whole lighter. By being able to use a thinner metal blade. Latest knife design - The Aggressor
