I was watching predator 2 last night at television and my mind has begin to freak out a little because of the coolest claws ever seen to me. and i wish to know something is it possible to control the claws like a cat by springs or by small hydrolic pumps,and all of that should fit in a 5 cm thick bracer or less/more.

and the last thing who would be able to do this : http://ahp.yautja.net/equipment/wristblades.jpg

It is a cool idea but teh only thing that bothers me is the fact it will more than likely be very illegal depending on where you live. I could see it comeing into conflict with "automatic' knife laws and "punch dagger" laws :(
