Can someone send the methods of how-it-work of the famous weapon of AC2: The Hidden Blade(Modern blade, not altair's)to show me how is it built? I really don't know how that work, and I'm planning to build one. Automatic mechanism, of course. I look in davinci's sketch on the teaser and see the clockwork. Anyone, the designer of that weapon, would you kindly enlighten the secret of the hidden blade for me, please?
*and altair's hidden blade, if you can.
