The 4051,4052 and 4053 were very static sensitive. But
it
is try that most were relatively insensitive. Still, if you
are hitting a part with a spark large enough to make
a sound, you are most likely doing some damage, even if
it doesn't show right away.
Duiring the '70s and '80s I worked at a company that made
many military and space grade components. A percentage
were de-lidded at the end of each lot and sent to a SEM
(Scanning Electron Microscope) to look for static damage,
that had NOT effected functionallity. If any (above a very
small threshold) was found, the ENTIRE lot was scrapped
[although they really became samples, lab grade, etc...]
It was AMAZING, the various craters and cracks that were
caused by static that you could not see, feel, or hear....
Wish I still had some of the prints....
