> In your opinion.  Others hold a different opinion.  While security through obscurity doesn't help in many circumstances, there are physical security controls that absolutely depend upon it, and work.  Physical lock and key, for one (the pinning must be kept obscure).  Physical combination locks, for another; they depend upon keeping the gates in the wheels obscure.  For that matter, any security that depends on any 'secret' is in essence a security through obscurity technique.  Port knocking is a security through obscurity technique (which works quite well).

you're talking about hiding the lock itself in a chinese puzzlebox, not 
hiding the tumblers inside the lock.
