There's definitely some I haven't seen.
The torx one that is tamper proof is commonly used in computer arenas, also known as security torx.

I'm quite sure there will still be some missing, I don't think all the tri-wings are there, I know you also get a straight triangle, and a curvey triangle

this one is slightly different to the tri-wing shown

It looks to me the same as the second one down, second from right, just tilt your head to the left!

I didn’t know about several of those. I’m guessing some are for specific applications and some didn’t gain enough popularity to catch on.

I remember the clutch drive on 50s vintages cars. I can’t remember if they carried over to 60s models. I don’t think I’ve seen them since then. There might be a few others that are outdated or obsolete.

Someone I consider a master woodworker once told me that a master woodworker is not someone who never makes mistakes. He is someone who is able to cover them up so that no one can tell.

I bought a set of 'security' bits in a rubber holder. Many of those are in the set. I haven't used 90% of them but the security torx were worth the price of the set.

Many screws look like phillips but aren't... the cause of many stripped screws IMO.
