This business card features an actual working set of lock picks.  Twist the tools to detach them.  The inventor’s site describes, “A hacker, entrepreneur, and all around mischief maker, Melvin wanted something he could give to peers and prospective clients that spoke of this nature. A lockpick concept was chosen very early on, and the post production results were excellent. The picks can quite easily be removed from the card and are entirely functional as lockpicks.”
