Interesting YouTube video on screwdrivers...

Really so.....
The small cross-slotted screws found on cameras are a variation on the Phillips, but unique in that they require a special screw driver.
There are even variations within the Phillips drive head. Apex Tool makes a Phillips driver head which is flat on the tip, so that it's more difficult to cam out. I worked at Ford, and the assembly plants used Apex drivers and bits exclusively.
But no Torx security screwdriver head bits there though. (pin in centre of hole in the bit). Had me head-scratching a while ago trying to use a normal Torx .. Now equipped to deal with all though!
But perhaps Ted was hoping for us to comment on the photographic attributes of the screwdriver heads picture rather than the many different types of head?
The Robertson screwdrivers have another unique feature that the video did not mention; the come in four sizes and they are identified by colour; from largest to smallest they go black, red, green and yellow. Red is probably the most common, followed by green. The black seems to be missing in your set.
They definitely do not cam out nearly as easily as Philips.
Top left second one down looks like a Phillips in a group of torx bits. As I recall there are two styles of bit that looks like Phillips, but on one the tip is blunted whereas the Phillips comes more to a point. Reed & Freerson or something like that was the more bout type.

Well spotted. That's the one I was referring to, E.
From your description, looks like I've swapped a couple of cross-points too ...As I recall there are two styles of bit that looks like Phillips, but on one the tip is blunted whereas the Phillips comes more to a point. Reed & Freerson or something like that was the more blunt type.

There are a few I've never heard of that I think I should have.
Good link, Dan, thanks.
My first encounter with a Torx driver was when upgrading a 128K RAM Macintosh to a whopping 512K thereby turning it into a 'Fat Mac'. The memory card seller included a very long and very necessary Torx screwdriver which he trusted you to send back when done!
