I know this thread is a couple of years old, but I saw it and had to comment...
Back in the late 90's to early 2000's, AT&T / Bell Labs Innovations / Lucent Technologies used to use these very same screw drivers, as well as a number of other products by Sandvik Belzer.
The picture above is one of their ESD screw drivers -- I know because I still have 3 of mine from that time -- a BE-8600 (small phillips), a BE-8610 (larger phillips), and a BE-8030 (small flat head, same length as the BE-8610).
These things have been used for many MANY years on many MANY electronics. The tips are magnetic, so that you can hold and insert screws directly into areas you could not get your hands or fingers into...
I need to find more of these....my three are sitting right here on my desk still, right where I used them last earlier this week....
Thanks for the history lesson about who purchased who and what...now to track some more of these down.... ;}
